Meta Starts Eliminating Jobs in Shift To Find AI Talent (msn.com) 64

Meta began notifying staff of job cuts on Monday, kick-starting a process that will terminate thousands of people as the company cracks down on "low-performers" and scours for new talent to dominate the AI race. From a report: Meta workers who were let go were notified via email, and the company is offering US-based employees severance packages that include 16 weeks of salary, in addition two weeks for each year of service, according to people familiar with the matter, who asked not to be named because the details weren't public. Employees whose review merited a bonus will still get one, and staff will still receive stock awards as part of the upcoming vesting cycle later this month, the people said.

Chief Executive Officer Mark Zuckerberg told employees that Meta would cut 5% of its workforce -- as many 3,600 people -- with a focus on staff who "aren't meeting expectations," Bloomberg News first reported in mid-January. Affected US-based employees would be notified on Feb. 10, while international employees could learn later, Zuckerberg said last month. In a separate message to managers, the Facebook co-founder said the cuts would create headcount for the company to hire the "strongest talent."

US-Funded 'Social Network' Attacking Pesticide Critics Shuts Down (theguardian.com) 64

The US company v-Fluence secretly compiled profiles on over 500 food and environmental health advocates, scientists, and politicians in a private web portal to discredit critics of pesticides and GM crops. Following public backlash and corporate cancellations after its actions were revealed by the Guardian, the company announced it was shutting down the profiling service. The Guardian reports: The profiles -- part of an effort that was financed, in part, by US taxpayer dollars -- often provided derogatory information about the industry opponents and included home addresses and phone numbers and details about family members, including children. They were provided to members of an invite-only web portal where v-Fluence also offered a range of other information to its roster of more than 1,000 members. The membership included staffers of US regulatory and policy agencies, executives from the world's largest agrochemical companies and their lobbyists, academics and others.

The profiling was one element of a push to downplay pesticide dangers, discredit opponents and undermine international policymaking, according to court records, emails and other documents obtained by the non-profit newsroom Lighthouse Reports. Lighthouse collaborated with the Guardian, the New Lede, Le Monde, Africa Uncensored, the Australian Broadcasting Corporation and other international media partners on the September 2024 publication of the investigation. News of the profiling and the private web portal sparked outrage and threats of litigation by some of the people and organizations profiled. [...]

v-Fluence says it not only has eliminated the profiling, but also has made "significant staff cuts" after the public exposure, according to Jay Byrne, the former Monsanto public relations executive who founded and heads the company. Byrne blamed the company's struggles on "rising costs from continued litigator and activist harassment of our staff, partners, and clients with threats and misrepresentations." He said the articles published about the company's profiling and private web portal were part of a "smear campaign" which was based on "false and misleading misrepresentations" that were "not supported by any facts or evidence." Adding to the company's troubles, several corporate backers and industry organizations have cancelled contracts with v-Fluence, according a post in a publication for agriculture professionals.

Citing EV 'Rollercoaster' In US, BMW Invests In Internal Combustion (msn.com) 241

An anonymous reader quotes a report from the Financial Times: BMW has pledged to continue investing in combustion engine and hybrid technology as it warned of a "rollercoaster ride" in the US transition to electric vehicles following the return of Donald Trump as president. Board member Jochen Goller said the group remained optimistic about sales of petrol and plug-in hybrids in the US even if demand for EVs slowed over the next few years on the back of policy changes under the new administration.

"I think it would be naive to believe that the move towards electrification is a one-way road. It will be a rollercoaster ride," Goller, who is in charge of customer, brands, and sales, told the Financial Times at BMW's headquarters in Munich. "This is why we are investing in our combustion engines," he said. "We are investing in modern plug-in hybrids. And we will continue rolling out electric cars."
BMW faces significant challenges in the Chinese market, with a 13% decline in sales amid intensifying price competition and growing dominance of domestic brands. Analysts note that while the company still sees China as a growing market, pricing pressures and an overcrowded automotive sector pose ongoing risks to BMW's long-term positioning.

It'll likely become even more difficult for BMW and other automotive companies to gain market share in the Chinese market with BYD's latest announcement. The Chinese automaker said it will be offering its advanced "God's Eye" autonomous technology in mass-market EVs like the $9,500 Seagull, while expanding globally with government-based EV initiatives.

China's BYD Adding 'High-Level' Self-Driving To Its Budget $10K EV (gizmodo.com) 48

Chinese automaker BYD is offering its advanced "God's Eye" autonomous technology in mass-market EVs like the $9,500 Seagull, while expanding globally with government-backed EV initiatives. Gizmodo reports: Previously, BYD had limited its driver assistance features to higher-end models that cost more than $28,000, according to BYD CEO Wang Chuanfu. In expanding the technology to the Seagull and other cars for no extra charge, Chuanfu said "good technology should be available to everyone." Other BYD vehicles getting the addition of the technology including cars from its Ocean, Han, Song, and Yuan lineups, as well as its hybrid vehicles. "God's Eye was developed in-house by BYD and will equip the automaker's mass-market models with features commonly only found on upscale EVs such as remote parking via smartphones and autonomous overtaking on roads," the company said.

BYD says the level of autonomy present in each car will vary depending on which sensors are equipped in the cars. Some of its pricier cars, for instance, include LiDAR sensors like those found in Waymos, which can offer faster and more precise object detection than cameras alone, particularly in low-light conditions or when a roadway is obstructed by rain or fog. [...] China's government has heavily prioritized the transition to electric vehicles with strong incentives, and BYD has managed to turn a profit on its electric vehicles, a feat that has heretofore only been accomplished by Tesla. The importance to China is clear: As the world continues transitioning to EVs, the likes of BYD have been able to push into markets including Europe and South America as Western brands lose share.

Jeep Introduces Pop-Up Ads That Appear Every Time You Stop (techstory.in) 192

"In-dash advertising is here and Stellantis, the parent company of Jeep, Dodge, Chrysler, and Ram, beat everyone to further enshittification," writes longtime Slashdot reader sinij. "Ads can be seen in this video." From a report: In a move that has left drivers both frustrated and bewildered, Stellantis has introduced full-screen pop-up ads on its infotainment systems. Specifically, Jeep owners have reported being bombarded with advertisements for Mopar's extended warranty service. The kicker? These ads appear every time the vehicle comes to a stop. Imagine pulling up to a red light, checking your GPS for directions, and suddenly, the entire screen is hijacked by an ad. That's the reality for some Stellantis owners. Instead of seamless functionality, drivers are now forced to manually close out of ads just to access basic vehicle functions.

One Jeep 4xe owner recently shared their frustration on an online forum, detailing how these pop-ups disrupt the driving experience. Stellantis, responding through their "JeepCares" representative, confirmed that these ads are part of the contractual agreement with SiriusXM and suggested that users simply tap the "X" to dismiss them. While the company claims to be working on reducing the frequency of these interruptions, the damage to customer trust may already be done.

UPDATE: Jeep Claims 'Software Glitch' Disabled Opting-Out of In-Vehicle Pop-Up Ads in 'a Few' Cases

TikTok Wants Android Users To Sideload Its App (techcrunch.com) 28

With TikTok's U.S. ban temporarily paused, the company is encouraging Android users to sideload its app by downloading it directly from TikTok.com as an APK file, bypassing the Google Play Store. TechCrunch reports: The Android app download is being made available as an Android Package Kit, more commonly known as an APK file, which contains the app's code, assets, and other resources that TikTok needs to run. By offering a standalone download, TikTok can at least temporarily skirt the current app store ban, which still prevents both Google Play and Apple's App Store from hosting the app while the ban's enforcement remains paused.

Brave Now Lets You Inject Custom JavaScript To Tweak Websites (bleepingcomputer.com) 12

Brave Browser version 1.75 introduces "custom scriptlets," a new feature that allows advanced users to inject their own JavaScript into websites for enhanced customization, privacy, and usability. The feature is similar to the TamperMonkey and GreaseMonkey browser extensions, notes BleepingComputer. From the report: "Starting with desktop version 1.75, advanced Brave users will be able to write and inject their own scriptlets into a page, allowing for better control over their browsing experience," explained Brave in the announcement. Brave says that the feature was initially created to debug the browser's adblock feature but felt it was too valuable not to share with users. Brave's custom scriptlets feature can be used to modify webpages for a wide variety of privacy, security, and usability purposes.

For privacy-related changes, users write scripts that block JavaScript-based trackers, randomize fingerprinting APIs, and substitute Google Analytics scripts with a dummy version. In terms of customization and accessibility, the scriptlets could be used for hiding sidebars, pop-ups, floating ads, or annoying widgets, force dark mode even on sites that don't support it, expand content areas, force infinite scrolling, adjust text colors and font size, and auto-expand hidden content.

For performance and usability, the scriptlets can block video autoplay, lazy-load images, auto-fill forms with predefined data, enable custom keyboard shortcuts, bypass right-click restrictions, and automatically click confirmation dialogs. The possible actions achievable by injected JavaScript snippets are virtually endless. However, caution is advised, as running untrusted custom scriptlets may cause issues or even introduce some risk.

Nvidia's RTX 5090 Power Connectors Are Melting (arstechnica.com) 86

An anonymous reader quotes a report from Ars Technica: Two owners of Nvidia's new RTX 5090 Founders Edition GPUs have reported melted power connectors and damage to their PSUs. The images look identical to reports of RTX 4090 power cables burning or melting from two years ago. Nvidia blamed the issue on people not properly plugging the 12VHPWR power connection in fully and the PCI standards body blamed Nvidia.

A Reddit poster upgraded from an RTX 4090 to an RTX 5090 and noticed "a burning smell playing Battlefield 5," before turning off their PC and finding the damage. The images show burnt plastic at both the PSU end of the power connector and the part that connects directly to the GPU. The cable is one from MODDIY, a popular manufacturer of custom cables, and the poster claims it was "securely fastened and clicked on both sides (GPU and PSU)." While it's tempting to blame the MODDIY cable, Spanish YouTuber Toro Tocho has experienced the same burnt cable (both at the GPU and PSU ends) with an RTX 5090 Founders Edition while using a cable supplied by PSU manufacturer FSP. Plastic has also melted into the PCIe 5.0 power connector on the power supply.

Reclassification Is Making US Tech Job Losses Look Worse Than They Are (theregister.com) 68

According to consultancy firm Janco, the U.S. Bureau of Labor Statistics reclassified several job titles, "leading to a downward adjustment of over 111,000 positions for November and December 2024," The Register reports. This revision contributed to an overall decline of 123,000 IT jobs for the year. However, in reality, IT sector hiring is on the rise, with 11,000 new positions added in January. From the report: "Many CEOs have given CFOs and CIOs the green light to hire IT Pros," Janco CEO Victor Janulaitis said of the first month of 2025. "IT Pros who were unemployed last month found jobs more quickly than was anticipated as CIOs rushed to fill open positions." There's still a 5.7 percent unemployment rate in the IT sector in January, Janco noted, which is greater than the national average of 4 percent - and which could rise further as Elon Musk's Department of Government Efficiency (DOGE) pushes ahead with federal workforce reductions aimed at streamlining operations.

"Over the past several quarters much of the overall job growth was in the government sectors of the economy," Janulaitis said. "With the new administration that will in all probability not be the case in the future. "The impact of the DOGE initiatives has not been felt as of yet," Janulaitis added. "Economic uncertainty continues to hurt overall IT hiring." Despite this, Janco reported an addition of 11,000 new IT roles in January. Unfortunately, there's also been a surge in IT unemployment over the same period, with the number of jobless IT pros rising to 152,000 in January - an increase of 54,000 in a single month. [...]

Closing out the report, Janco offered a mixed outlook: While IT jobs are expected to grow over the next few years, many white-collar roles could be eliminated. "Over the next five years, the number of individuals employed as IT professionals will increase while many white-collar jobs in the function will be eliminated with the application of AI and LLM to IT," Janco predicted.

Microchip Company Ceases Operations, Pet Owners Urged To Re-Register (cbsnews.com) 37

An anonymous reader quotes a report from CBS News: Animal shelters, rescues, and veterinarian clinics around the U.S. are posting on social media telling pet owners to check their four-legged friends' microchips after learning a major microchip company [called Save This Life] is no longer providing services. [...] If you're unsure which company your cats or dogs' chips are registered with, check them. "You can go to your local veterinarian office, a local police station, or even a local animal shelter like HARP, and we can help check that for you and scan your animal. And then you take that number that's on there and there's a tool online where you can go look it up," [said Dan Cody, Executive Director of Humane Animal Rescue of Pittsburgh].

He said you check the number by using the AAHA Universal Microchip Lookup Tool at this link. If you discover your pet's microchip was registered to the company that's ceased operations, you'll need to register with a different company. "So, if you find that you are affected by this, you're going to want to go to one of these other websites that do the registrations. So, things like AKC Reunite, and PetLink. 24PetWatch these are all large companies who've been around for a long time and have good reputations," said Cody.

The American Kennel Club shared a post from its AKC Reunite Facebook page, encouraging people to enroll in microchips with AKC Reunite. The post said in part, "If your dog or cat has a microchip number that starts with 991 or 900164 then it could be a Save This Life microchip. Save This Life suddenly closed, and your pet may not be protected." Cody said if your furry best friend isn't microchipped, take them to a vet or shelter like HARP to get one implanted under their skin so they have a permanent ID. Microchipping can be done at HARP's East Side and North Side Veterinary Medical Center by appointment.

Lyft Eyes Robotaxi Launch in 2026 27

Lyft says it will launch a fleet of robotaxis, using self-driving technology from Intel's Mobileye, in Dallas in "as soon as 2026," with plans to scale to "thousands" of vehicles in additional markets in the months to follow. From a report: To signal its seriousness, the company tapped Marubeni, a Japanese conglomerate, to run fleet operations. Lyft's news comes after Uber dropped new details about its plan to feature Waymo's robotaxis on its platform in Austin and Atlanta later this year. And Tesla recently shared plans to launch a robotaxi service in Austin this summer.

OpenAI Set To Finalize First Custom Chip Design This Year (reuters.com) 15

OpenAI is pushing ahead on its plan to reduce its reliance on Nvidia for its chip supply by developing its first generation of in-house AI silicon. From a report: The ChatGPT maker is finalizing the design for its first in-house chip in the next few months and plans to send it for fabrication at Taiwan Semiconductor Manufacturing Co, sources told Reuters. The process of sending a first design through a chip factory is called "taping out."

The update shows that OpenAI is on track to meet its ambitious goal of mass production at TSMC in 2026. A typical tape-out costs tens of millions of dollars and will take roughly six months to produce a finished chip, unless OpenAI pays substantially more for expedited manufacturing. There is no guarantee the silicon will function on the first tape out and a failure would require the company to diagnose the problem and repeat the tape-out step. Inside OpenAI, the training-focused chip is viewed as a strategic tool to strengthen OpenAI's negotiating leverage with other chip suppliers, the sources said.

DeepMind Chief Dismisses DeepSeek's AI Breakthrough as 'Known Techniques' (cnbc.com) 30

Google DeepMind CEO Demis Hassabis downplayed the technological significance of DeepSeek's latest AI model, despite its market impact. "Despite the hype, there's no actual new scientific advance there. It's using known techniques," Hassabis said on Sunday. "Actually many of the techniques we invented at Google and at DeepMind."

Hassabis acknowledged that Deepseek's AI model "is probably the best work" out of China, but its capabilities, he said, is "exaggerated a little bit."DeepSeek's launch last month triggered a $1 trillion U.S. market sell-off.

Skydiver Hooks Plane in Mid-Air, Gets Towed Up For Another Skydive (newatlas.com) 21

"Can you skydive continuously without landing...?" asks Red Bull. Imagine jumping out of a helicopter, "only to latch onto a speeding plane in mid-air and soar back up into the sky." Harnessing the plane's momentum, [skydiver Max Manow] soared out of the canyon, embarking on what he calls his "endless skydive", a manoeuvre that potentially could be done continuously without him ever needing to land...

After exiting a helicopter, he manoeuvred his wingsuit to close the gap with a nosediving Cessna 182, piloted by Luke Aikins. Precision was key: Manow attached himself to a hook on the aircraft as the plane descended, allowing him to ascend back to a safe altitude of 2,500 feet before releasing into another freefall... Manow spent five months training, including sessions in a Stockholm wind tunnel, to master the techniques needed for mid-air connection. Meanwhile, Aikins modified his aircraft to ensure the feat was safe and repeatable.

Skydiver Max Manow's goal was to develop a manoeuvre that could potentially be repeated an infinite number of times without ever having to land. Manow's mid-air manoeuvre opens the door to a new vision of skydiving, where athletes could remain airborne without ever needing to land. Reflecting on the experience, Manow said: "Who knows where this will take the future of the sport?"

"If that wasn't enough adrenaline for you," writes New Atlas, "a previous bonkers wingsuit stunt from 2017 is equally jaw dropping, in which a pair of skydivers BASE-jumped off a mountain summit, and entered a passing airplane."

Did Google Fake Gemini AI's Output For Its Super Bowl Ad? (theverge.com) 43

Google's Super Bowl ad about a Gouda cheese seller appears to be using fake AI output, writes the Verge: The text portrayed as generated by AI has been available on the business's website since at least August 2020, as shown on this archived webpage. Google didn't launch Gemini until 2023, meaning Gemini couldn't have generated the website description as depicted in the ad.
The site Futurism calls the situation "beyond bizarre," asking why Google doesn't seem to trust its own technology. Either Google faked the ad entirely, or prompted its AI to generate the web page's existing copy word-for-word, or the AI was prompted to come up with original copy and instead copied the old version. In the publishing industry, that's referred to as "plagiarism."
And ironically if Gemini did plagiarize that text, the text that it plagiarized is also inaccurate.

While TikTok Buys Ads on YouTube, YouTube is Buying Ads on TikTok (yahoo.com) 30

I just saw an ad for TikTok on a YouTube video. But at the same time YouTube is running ads on TikTok, reports Bloomberg, targeting TikTok content creators in "an effort to lure these valuable users to the Google-owned rival and capitalize on TikTok's uncertain future."

One of YouTube's ads even received over a thousand likes, with Bloomberg calling it that TikTok "is willing to accept ad dollars from one of its fiercest competitors promoting a message aimed at undercutting its business." YouTube is the latest TikTok competitor to try to capitalize on the app's looming US ban, which could go into effect in early April. Meta Platforms Inc.'s Instagram announced a new video editing tool in January, and X also teased a new video tab as part of an effort to win over TikTok's content creators...

Google would be one of the biggest beneficiaries of a ban in the US. Both its flagship video service YouTube and its TikTok copycat, YouTube Shorts, would likely see an uptick in traffic if TikTok goes away. Google also plays an unusual role in TikTok's potential ban because it runs one of two mobile app stores controlling whether people in the US can download the video app. It has blocked TikTok from its Google Play store since the divest-or-ban law went into effect January 19.

Volkswagen Announces a Cheap Electric Car to Compete With China (telegraph.co.uk) 102

An anonymous reader shared this report from the Telegraph: Volkswagen has teased plans for a "China-killer" electric vehicle that will cost just €20,000 ($20,664 USD or £16,700) as the German carmaker gears up to take on a flood of Beijing-backed low-cost rivals. The company on Thursday shared its first images of a new vehicle expected to be called the ID.1, which will go into production from 2027.

The low-cost EV is intended to go head to head with all-electric brands from Chinese carmakers such as BYD, which overtook Tesla in British sales for the first time last month. Previous images of the vehicle suggest it will be an electric hatchback. Thomas Schäfer, the VW chief executive, said the new model would be "an affordable, high-quality, profitable electric Volkswagen from Europe, for Europe". Quentin Willson, the motoring journalist and founder of FairCharge, said the car could be a "possible China EV killer". Dan Caesar, of Electric Vehicles UK, added: "Cheaper EVs are exactly what legacy auto-makers need to be competitive during this critical time. We would expect the ID.1 to be warmly welcomed by motorists." Ginny Buckley, of consumer advice website Electrifying, said Volkswagen had been "clear about its intent to compete with China's low-cost EVs"...

The German carmaker is planning to cut 35,000 jobs by 2030 as it grapples with stalled demand for EVs in Europe and growing competition from Chinese rivals.

Volkswagen executives describe the upcoming EV will be a "true Volkswagen for everyone," according to the article

It also notes that the number of EVs sold across Europe "fell by 3% to 3 million during 2024, according to data from analysts Rho Motion."

White House Moves to Halt Federal Funds for EV Charging Stations (politico.com) 288

Thursday the White House "moved to halt a $5 billion initiative to build electric vehicle charging stations," reports Politico, "by instructing states not to spend federal funds previously allocated to them..." NPR described the move as "putting in limbo billions of dollars allocated to states with current and future projects..."

Politico notes the move "appears to upend years of precedent in which federal promises of funds for highway projects had given states an all-but-guaranteed assurance that they were free to spend them. It also raises legal questions... Funding experts had told POLITICO last year that decades of legal precedent would largely insulate the charging money... Andrew Rogers [deputy administrator of the Federal Highway Administration, or FHWA, in the Biden administration] said in a text message that the new letter "appears to ignore both the law and multiple restraining orders that have been issued by federal courts." Rogers, who is now a senior vice president at Boundary Stone Partners, said the move appears to be "in direct violation" of the Impoundment Control Act of 1974, a Watergate-era law that prohibits presidents from unilaterally canceling congressionally approved spending. Trump has contended that the law is unconstitutional.
Politico also got a quote from the chief analyst at analytics firm Paren, who predicts lawsuits from affected states and that the final impact of the move will be "just causing havoc and slowing things down for awhile." [A letter to state transportation directors from the Federal Highway Administration] clarifies that states will be able to receive reimbursements for "existing obligations" to design and build stations "in order to not disrupt current financial commitments." According to the letter, FHWA plans to publish new draft guidance on the NEVI program in the spring, followed by a comment period, before issuing new final guidance. Only then will states be able to resubmit their annual implementation plans for all fiscal years of the program.
"But that doesn't mean that the program is going to be sunset or the funds are not going to be made available again to the states," Nick Nigro, the founder of Atlas Public Policy consultancy told NPR: Several experts tell NPR that as a result of its overwhelming bipartisan support at the time, attempts to overturn it within the executive branch are likely to be challenged in court. Nigro believes the funding will resume eventually...

So far, 56 stations [with multiple chargers] are up and running as a result of the program, while more than 900 sites in total have been "awarded" to date, according to Loren McDonald, chief analyst at Paren, another research analytics firm. McDonald said several hundred of the awarded sites are currently under construction and expected to open this year. He does not believe the FHWA has the authority to pause or rescind any aspect of the NEVI program... "I assume lawsuits from states will start soon, and this will go to court and Congress," McDonald said in a statement.

The move has "confounded states, which had been allocated billions of dollars by Congress for the program," the New York Times reported Friday. "[S]ome state officials said that as a result of the memo from the Trump administration, they had stopped work on the charging stations. Others said they intended to keep going."

The Washington Post reports that a Texas Department of Transportation official "said it would continue to deploy federal funds for EV chargers until it receives further guidance," and that Ryan Gallentine, managing director at the national business association Advanced Energy United, said that states "are under no obligation to stop these projects based solely on this announcement." Politico adds: Also on Thursday, FHWA took down several internet pages providing information on NEVI and its sister program, the $2.5 billion Charging and Fueling Infrastructure grant program... Amid the confusion, at least six states — Alabama, Oklahoma, Missouri, Rhode Island, Ohio and Nebraska — have put their NEVI programs on hold, according to McDonald. Rhode Island and Ohio had been considered leading states in implementing the program.

Quantum Teleportation Used To Distribute a Calculation (arstechnica.com) 58

An anonymous reader quotes a report from Ars Technica: In today's issue of Nature, a team at Oxford University describes using quantum teleportation to link two pieces of quantum hardware that were located about 2 meters apart, meaning they could easily have been in different rooms entirely. Once linked, the two pieces of hardware could be treated as a single quantum computer, allowing simple algorithms to be performed that involved operations on both sides of the 2-meter gap. [...] The Oxford team was simply interested in a proof-of-concept, and so used an extremely simplified system. Each end of the 2-meter gap had a single trap holding two ions, one strontium and one calcium. The two atoms could be entangled with each other, getting them to operate as a single unit.

The calcium ion served as a local memory and was used in computations, while the strontium ion served as one of the two ends of the quantum network. An optical cable between the two ion traps allowed photons to entangle the two strontium ions, getting the whole system to operate as a single unit. The key thing about the entanglement processes used here is that a failure to entangle left the system in its original state, meaning that the researchers could simply keep trying until the qubits were entangled. The entanglement event would also lead to a photon that could be measured, allowing the team to know when success had been achieved (this sort of entanglement with a success signal is termed "heralded" by those in the field).

The researchers showed that this setup allowed them to teleport with a specific gate operation (controlled-Z), which can serve as the basis for any other two-qubit gate operation -- any operation you might want to do can be done by using a specific combination of these gates. After performing multiple rounds of these gates, the team found that the typical fidelity was in the area of 70 percent. But they also found that errors typically had nothing to do with the teleportation process and were the product of local operations at one of the two ends of the network. They suspect that using commercial hardware, which has far lower error rates, would improve things dramatically. Finally, they performed a version of Grover's algorithm, which can, with a single query, identify a single item from an arbitrarily large unordered list. The "arbitrary" aspect is set by the number of available qubits; in this case, having only two qubits, the list maxed out at four items. Still, it worked, again with a fidelity of about 70 percent.

While the work was done with trapped ions, almost every type of qubit in development can be controlled with photons, so the general approach is hardware-agnostic. And, given the sophistication of our optical hardware, it should be possible to link multiple chips at various distances, all using hardware that doesn't require the best vacuum or the lowest temperatures we can generate. That said, the error rate of the teleportation steps may still be a problem, even if it was lower than the basic hardware rate in these experiments. The fidelity there was 97 percent, which is lower than the hardware error rates of most qubits and high enough that we couldn't execute too many of these before the probability of errors gets unacceptably high.
