Iran Bans Officials From Using Internet-Connected Devices (timesofisrael.com) 68

An anonymous reader shares a report: Iran's cybersecurity authority has banned officials from using devices that connect to the internet, apparently fearing being tracked or hacked by Israel. According to the state-linked Fars news agency, Iranian officials and their bodyguards have been told they are not allowed to use any equipment that connects to public internet or telecommunications networks.

'Firefox Is Dead To Me' (theregister.com) 240

Veteran columnist Steven J. Vaughan-Nichols declared that Firefox was "dead" to him in a scathing opinion piece Tuesday that cites Mozilla's strategic missteps and the browser's declining technical performance as evidence of terminal decline. Vaughan-Nichols argues that Mozilla has fundamentally betrayed user trust by removing a longstanding promise never to sell personal data from its privacy policy in February, replacing it with a weaker pledge to "protect your personal information."

The veteran technology writer also criticized Mozilla's decision to discontinue Pocket, a popular article-saving service, and Fakespot, which identified fake online reviews, while pursuing what he called a misguided AI strategy. He cited user reports of Firefox running up to 30% slower than Chrome, consuming excessive memory, and failing to properly load major websites. Mozilla has also become financially more vulnerable, he argued, noting CFO Eric Muhlheim's admission that the company depends on Google for 90% of its revenue. According to federal data he cited, Firefox holds just 1.9% of the browser market, leading him to conclude the browser is "done."

Denmark Tests Unmanned Robotic Sailboat Fleet (apnews.com) 10

Denmark has deployed four uncrewed robotic sailboats (known as "Voyagers") for a three-month trial to boost maritime surveillance amid rising tensions in the Baltic region. The Associated Press reports: Built by Alameda, California-based company Saildrone, the vessels will patrol Danish and NATO waters in the Baltic and North Seas, where maritime tensions and suspected sabotage have escalated sharply since Russia's full-scale invasion of Ukraine on Feb. 24, 2022. Two of the Voyagers launched Monday from Koge Marina, about 40 kilometers (25 miles) south of the Danish capital, Copenhagen. Powered by wind and solar energy, these sea drones can operate autonomously for months at sea. Saildrone says the vessels carry advanced sensor suites -- radar, infrared and optical cameras, sonar and acoustic monitoring. Their launch comes after two others already joined a NATO patrol on June 6.

Saildrone founder and CEO Richard Jenkins compared the vessels to a "truck" that carries sensors and uses machine learning and artificial intelligence to give a "full picture of what's above and below the surface" to about 20 to 30 miles (30 to 50 kilometers) in the open ocean. He said that maritime threats like damage to undersea cables, illegal fishing and the smuggling of people, weapons and drugs are going undetected simply because "no one's observing it." Saildrone, he said, is "going to places ... where we previously didn't have eyes and ears." The Danish Defense Ministry says the trial is aimed at boosting surveillance capacity in under-monitored waters, especially around critical undersea infrastructure such as fiber-optic cables and power lines.

Social Media Now Main Source of News In US, Research Suggests (bbc.com) 169

An anonymous reader quotes a report from the BBC: Social media and video networks have become the main source of news in the US, overtaking traditional TV channels and news websites, research suggests. More than half (54%) of people get news from networks like Facebook, X and YouTube -- overtaking TV (50%) and news sites and apps (48%), according to the Reuters Institute. "The rise of social media and personality-based news is not unique to the United States, but changes seem to be happening faster -- and with more impact -- than in other countries," a report found. Podcaster Joe Rogan was the most widely-seen personality, with almost a quarter (22%) of the population saying they had come across news or commentary from him in the previous week. The report's author Nic Newman said the rise of social video and personality-driven news "represents another significant challenge for traditional publishers." Other key findings from the report include:
- TikTok is the fastest-growing social and video platform, now used for news by 17% globally (up 4% from last year).
- AI chatbot use for news is increasing, especially among under-25s, where it's twice as popular as in the general population.
- Most people believe AI will reduce transparency, accuracy, and trust in news.
- Across all age groups, trusted news brands with proven accuracy remain valued, even if used less frequently.

Google Cloud Caused Outage By Ignoring Its Usual Code Quality Protections (theregister.com) 42

Google Cloud has attributed last week's widespread outage to a flawed code update in its Service Control system that triggered a global crash loop due to missing error handling and lack of feature flag protection. The Register reports: Google's explanation of the incident opens by informing readers that its APIs, and Google Cloud's, are served through our Google API management and control planes." Those two planes are distributed regionally and "are responsible for ensuring each API request that comes in is authorized, has the policy and appropriate checks (like quota) to meet their endpoints." The core binary that is part of this policy check system is known as "Service Control."

On May 29, Google added a new feature to Service Control, to enable "additional quota policy checks." "This code change and binary release went through our region by region rollout, but the code path that failed was never exercised during this rollout due to needing a policy change that would trigger the code," Google's incident report explains. The search monopolist appears to have had concerns about this change as it "came with a red-button to turn off that particular policy serving path." But the change "did not have appropriate error handling nor was it feature flag protected. Without the appropriate error handling, the null pointer caused the binary to crash."

Google uses feature flags to catch issues in its code. "If this had been flag protected, the issue would have been caught in staging." That unprotected code ran inside Google until June 12th, when the company changed a policy that contained "unintended blank fields." Here's what happened next: "Service Control, then regionally exercised quota checks on policies in each regional datastore. This pulled in blank fields for this respective policy change and exercised the code path that hit the null pointer causing the binaries to go into a crash loop. This occurred globally given each regional deployment."

Google's post states that its Site Reliability Engineering team saw and started triaging the incident within two minutes, identified the root cause within 10 minutes, and was able to commence recovery within 40 minutes. But in some larger Google Cloud regions, "as Service Control tasks restarted, it created a herd effect on the underlying infrastructure it depends on ... overloading the infrastructure." Service Control wasn't built to handle this, which is why it took almost three hours to resolve the issue in its larger regions. The teams running Google products that went down due to this mess then had to perform their own recovery chores.
Going forward, Google has promised a couple of operational changes to prevent this mistake from happening again: "We will improve our external communications, both automated and human, so our customers get the information they need asap to react to issues, manage their systems and help their customers. We'll ensure our monitoring and communication infrastructure remains operational to serve customers even when Google Cloud and our primary monitoring products are down, ensuring business continuity."

Vandals Cut Fiber-Optic Lines, Causing Outage For Spectrum Internet Subscribers (arstechnica.com) 49

An anonymous reader quotes a report from Ars Technica: Subscribers in Southern California of Spectrum's Internet service experienced outages over the weekend following what company officials said was an attempted theft of copper lines located in Van Nuys, a suburb located 20 miles from downtown Los Angeles. The people behind the incident thought they were targeting copper lines, the officials wrote in a statement Sunday. Instead, they cut into fiber optic cables. The cuts caused service disruptions for subscribers in Van Nuys and surrounding areas. Spectrum has since restored service and is offering a $25,000 reward for information leading to the apprehension of the people responsible. Spectrum will also credit affected customers one day of service on their next bill.

"Criminal acts of network vandalism have become an issue affecting the entire telecommunications industry, not just Spectrum, largely due to the increase in the price of precious metals," the officials wrote in a statement issued Sunday. "These acts of vandalism are not only a crime, but also affect our customers, local businesses and potentially emergency services. Spectrum's fiber lines do not include any copper." Outage information service Downdetector showed that thousands of subscribers in and around Van Nuys reported outages starting a little before noon on Sunday. Within about 12 hours, the complaint levels returned to normal. Spectrum officials told the Los Angeles Times that personnel had to splice thousands of fiber lines to restore service to affected subscribers.

Threads Will Let You Hide Spoilers In Your Posts (theverge.com) 40

Threads is testing a new feature that lets users hide spoiler content by blurring images or text, which can then be revealed with a tap. The Verge reports: Meta spokesperson Alec Booker told The Verge that this is a "global test," though it's not clear how many people will gain access to it. Spoilers will also look a bit different depending on which device you're using. On desktop, spoilers are hidden by a gray block, but they appear behind a bunch of floating dots on mobile (which you can see in the GIF embedded [here]). "This feature is currently optimized for mobile, but we're working to improve the experience for desktop," Booker said.

The US Navy Is More Aggressively Telling Startups, 'We Want You' (techcrunch.com) 20

An anonymous reader quotes a report from TechCrunch: While Silicon Valley executives like those from Palantir, Meta, and OpenAI are grabbing headlines for trading their Brunello Cucinelli vests for Army Reserve uniforms, a quieter transformation has been underway in the U.S. Navy. How so? Well, the Navy's chief technology officer, Justin Fanelli, says he has spent the last two and a half years cutting through the red tape and shrinking the protracted procurement cycles that once made working with the military a nightmare for startups. The efforts represent a less visible but potentially more meaningful remaking that aims to see the government move faster and be smarter about where it's committing dollars.

"We're more open for business and partnerships than we've ever been before," Fanelli told TechCrunch in a recent episode of StrictlyVC Download. "We're humble and listening more than before, and we recognize that if an organization shows us how we can do business differently, we want that to be a partnership." Right now, many of these partnerships are being facilitated through what Fanelli calls the Navy's innovation adoption kit, a series of frameworks and tools that aim to bridge the so-called Valley of Death, where promising tech dies on its path from prototype to production. "Your granddaddy's government had a spaghetti chart for how to get in," Fanelli said. "Now it's a funnel, and we are saying, if you can show that you have outsized outcomes, then we want to designate you as an enterprise service."

In one recent case, the Navy went from a Request for Proposal (RFP) to pilot deployment in under six months with Via, an eight-year-old, Somerville, Massachusetts-based cybersecurity startup that helps big organizations protect sensitive data and digital identities through, in part, decentralization, meaning the data isn't stored in one central spot that can be hacked. (Another of Via's clients is the U.S. Air Force.) The Navy's new approach operates on what Fanelli calls a "horizon" model, borrowed and adapted from McKinsey's innovation framework. Companies move through three phases: evaluation, structured piloting, and scaling to enterprise services. The key difference from traditional government contracting, Fanelli says, is that the Navy now leads with problems rather than predetermined solutions. "Instead of specifying, 'Hey, we'd like this problem solved in a way that we've always had it,' we just say, 'We have a problem, who wants to solve this, and how will you solve it?'" Fanelli said.

Windows Hello Face Unlock No Longer Works in the Dark and Microsoft Says It's Not a Bug (windowscentral.com) 23

Microsoft has disabled Windows Hello's ability to authenticate users in low-light environments through a recent security update that now requires both infrared sensors and color cameras to verify faces. The change forces the system to see a visible face through the webcam before completing authentication with IR sensors.

Windows Hello earlier relied solely on infrared sensors to create 3D facial scans, allowing the feature to work in complete darkness similar to iPhone's Face ID. Microsoft pushed the dual-camera requirement to address a spoofing vulnerability in the biometric system.

WhatsApp Introduces Ads in Its App (nytimes.com) 53

An anonymous reader shares a report: When Facebook bought WhatsApp for $19 billion in 2014, the messaging app had a clear focus. No ads, no games and no gimmicks. For years, that is what WhatsApp's two billion users -- many of them in Brazil, India and other countries around the world -- got. They chatted with friends and family unencumbered by advertising and other features found on social media. Now that is set to change.

On Monday, WhatsApp said it would start showing ads inside its app for the first time. The promotions will appear only in an area of the app called Updates, which is used by around 1.5 billion people a day. WhatsApp will collect some data on users to target the ads, such as location and the device's default language, but it will not touch the contents of messages or whom users speak with. The company added that it had no plans to place ads in chats and personal messages.

[...] In-app ads are a significant change from WhatsApp's original philosophy. Jan Koum and Brian Acton, who founded WhatsApp in 2009, were committed to building a simple and quick way for friends and family to communicate with end-to-end encryption, a method of keeping texts, photos, videos and phone calls inaccessible by third parties. Both left the company seven years ago. Since then, Mark Zuckerberg, the chief executive of Facebook, now Meta, has focused on WhatsApp's growth and user privacy while also melding the app into the company's other products, including Instagram and Messenger.

Walmart's Drone Deliveries Expand, Now in Five Different US States (cnbc.com) 44

"Walmart is bringing drone deliveries to three more states," reports CNBC: On Thursday, the big-box retailer said it plans to launch the speedier delivery option at 100 stores in Atlanta, Charlotte, Houston, Orlando and Tampa within the coming year. With the expansion, Walmart's drone deliveries will be available in a total of five states: [parts of northwest] Arkansas, Florida, Georgia, North Carolina and [the Dallas-Fort Worth area of] Texas... The drone operator will have an up to a six-mile range from stores.
Walmart tells CNBC the most frequently delivered items include ice cream, fresh fruit, and pet food, as well as "urgent items, such as hamburger buns for a cookout, eggs to make brownies or Tylenol or cold medicine needed when sick." It's all part of Walmart's effort to compete with Amazon: With more than 4,600 Walmart stores across the U.S., the retailer has used its large footprint to get online orders to customers faster. It has an Express Delivery service that drops purchases at customers' doors in as fast as 30 minutes, along with InHome, a subscription-based service, that puts items directly into people's fridges. The company began same-day prescription deliveries last fall and has expanded the service across the country.... Walmart stores have an assortment of over 150,000 items in a location. Over 50% of those can be delivered by drone, said Greg Cathey [Walmart's senior VP for U.S. transformation and innovation]...

Walmart's drone delivery count so far is modest. The company did not share the specific count, but said it has racked up a total of more than 150,000 drone deliveries since 2021.

LibreOffice Explains 'Real Costs' of Upgrading to Microsoft's Windows 11, Urges Taking Control with Linux (documentfoundation.org) 221

KDE isn't the only organization reaching out to " as Microsoft prepares to end support for Windows 10.

"Now, The Document Foundation, maker of LibreOffice, has also joined in to support the Endof10 initiative," reports the tech blog Neowin: The foundation writes: "You don't have to follow Microsoft's upgrade path. There is a better option that puts control back in the hands of users, institutions, and public bodies: Linux and LibreOffice. Together, these two programmes offer a powerful, privacy-friendly and future-proof alternative to the Windows + Microsoft 365 ecosystem."

It further adds the "real costs" of upgrading to Windows 11 as it writes:

"The move to Windows 11 isn't just about security updates. It increases dependence on Microsoft through aggressive cloud integration, forcing users to adopt Microsoft accounts and services. It also leads to higher costs due to subscription and licensing models, and reduces control over how your computer works and how your data is managed. Furthermore, new hardware requirements will render millions of perfectly good PCs obsolete.... The end of Windows 10 does not mark the end of choice, but the beginning of a new era. If you are tired of mandatory updates, invasive changes, and being bound by the commercial choices of a single supplier, it is time for a change. Linux and LibreOffice are ready — 2025 is the right year to choose digital freedom!"

The first words on LibreOffice's announcement? "The countdown has begun...."

Mitsubishi Launches EV Battery Swap Network in Tokyo - for Both Cars and Trucks (electrek.co) 70

In Tokyo Mitsubishi is deploying "an innovative new battery swap network for electric cars" in a multi-year test program reports the EV news site Electrek.

But it's not just for electric cars. Along with the 14 modular battery swapping stations, Mitsubishi is also deploying "more than 150 battery-swappable commercial electric vehicles" from truck maker Fuso: A truck like the Mitsubishi eCanter typically requires a full night of AC charging to top off its batteries, and at least an hour or two on DC charging in Japan, according to Fuso. This joint pilot by Mitsubishi, Mitsubishi Fuso Trucks, and [EV battery swap specialist] Ample aims to circumvent this issue of forced downtime with its swappable batteries, supporting vehicle uptime by delivering a full charge within minutes.

The move is meant to encourage the transport industry's EV shift while creating a depository of stored energy that can be deployed to the grid in the event of a natural disaster — something Mitsubishi in Japan has been working on for years.

The article's author also adds their own opinion about battery-swapping technology. "When you see how simple it is to add hundreds of miles of driving in just 100 seconds — quicker, in many cases, than pumping a tank of liquid fuel into an ICE-powered car — you might come around, yourself."

17-Year-Old Student Builds 3D-printed Drone In Garage, Interests DoD and MIT (yahoo.com) 63

"Cooper Taylor is only 17 years old, but he's already trying to revolutionize the drone industry," writes Business Insider: His design makes the drone more efficient, customizable, and less expensive to construct, he says. He's built six prototypes, 3D printing every piece of hardware, programming the software, and even soldering the control circuit board. He says building his drone cost one-fifth of the price of buying a comparable machine, which sells for several thousand dollars. Taylor told Business Insider he hopes that "if you're a first responder or a researcher or an everyday problem solver, you can have access to this type of drone."

His innovation won him an $8,000 scholarship in April at the Junior Science and Humanities Symposium, funded by the Defense Department. Then, on May 16, he received an even bigger scholarship of $15,000 from the US Navy, which he won after presenting his research at the Regeneron International Science and Engineering Fair...

It all started when Taylor's little sister got a drone, and he was disappointed to see that it could fly for only about 30 minutes before running out of power. He did some research and found that a vertical take-off and landing, or VTOL, drone would last longer. This type of drone combines the multi-rotor helicopter style with the fixed wings of an airplane, making it extremely versatile. It lifts off as a helicopter, then transitions into plane mode. That way, it can fly farther than rotors alone could take it, which was the drawback to Taylor's sister's drone. Unlike a plane-style drone, though, it doesn't need a runway, and it can hover with its helicopter rotors.

Taylor designed a motor "that could start out helicopter-style for liftoff, then tilt back to become an airplane-style motor," according to the article.

And now this summer he'll be "working on a different drone project through a program with the Reliable Autonomous Systems Lab at the Massachusetts Institute of Technology."

Executives from Meta, OpenAI, and Palantir Commissioned Into the US Army Reserve (theregister.com) 184

Meta's CTO, Palantir's CTO, and OpenAI's chief product officer are being appointed as lieutenant colonels in America's Army Reserve, reports The Register. (Along with OpenAI's former chief revenue officer).

They've all signed up for Detachment 201: Executive Innovation Corps, "an effort to recruit senior tech executives to serve part-time in the Army Reserve as senior advisors," according to the official statement. "In this role they will work on targeted projects to help guide rapid and scalable tech solutions to complex problems..." "Our primary role will be to serve as technical experts advising the Army's modernization efforts," [Meta CTO Andrew Bosworth] said on X...

As for Open AI's involvement, the company has been building its ties with the military-technology complex for some years now. Like Meta, OpenAI is working with Anduril on military ideas and last year scandalized some by watering down its past commitment to developing non-military products only. The Army wasn't answering questions on Friday but an article referenced by [OpenAI Chief Product Officer Kevin] Weil indicated that the four will have to serve a minimum of 120 hours a year, can work remotely, and won't have to pass basic training...

"America wins when we unite the dynamism of American innovation with the military's vital missions," [Palantir CTO Shyam] Sankar said on X. "This was the key to our triumphs in the 20th century. It can help us win again. I'm humbled by this new opportunity to serve my country, my home, America."

Do Biofuels Increase Greenhouse Gas Emissions? (arstechnica.com) 46

Will an expansion of biofuels increase greenhouse gas emissions, despite their purported climate benefits? That's the claim of a new report from the World Resources Institute, which has been critical of US biofuel policy in the past.

Ars Technica has republished an article from the nonprofit, non-partisan news organization Inside Climate News, which investigates the claim. Drawing from 100 academic studies on biofuel impacts, the Institute's new report "concludes that [U.S.] ethanol policy has been largely a failure and ought to be reconsidered, especially as the world needs more land to produce food to meet growing demand." "Multiple studies show that U.S. biofuel policies have reshaped crop production, displacing food crops and driving up emissions from land conversion, tillage, and fertilizer use," said the report's lead author, Haley Leslie-Bole. "Corn-based ethanol, in particular, has contributed to nutrient runoff, degraded water quality and harmed wildlife habitat. As climate pressures grow, increasing irrigation and refining for first-gen biofuels could deepen water scarcity in already drought-prone parts of the Midwest...."

It may, in fact, produce more greenhouse gases than the fossil fuels it was intended to replace. Recent research says that biofuel refiners also emit significant amounts of carcinogenic and dangerous substances, including hexane and formaldehyde, in greater amounts than petroleum refineries. The new report points to research saying that increased production of biofuels from corn and soy could actually raise greenhouse gas emissions, largely from carbon emissions linked to clearing land in other countries to compensate for the use of land in the Midwest.

On top of that, corn is an especially fertilizer-hungry crop requiring large amounts of nitrogen-based fertilizer, which releases huge amounts of nitrous oxide when it interacts with the soil. American farming is, by far, the largest source of domestic nitrous oxide emissions already — about 50 percent. If biofuel policies lead to expanded production, emissions of this enormously powerful greenhouse gas will likely increase, too.

Strange Radio Pulses Detected Coming From Ice In Antarctica (phys.org) 44

alternative_right shares a report from Phys.Org: A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere.

The goal of the experiment is to gain insight into distant cosmic events by analyzing signals that reach the Earth. Rather than reflecting off the ice, the signals -- a form of radio waves -- appeared to be coming from below the horizon, an orientation that cannot be explained by the current understanding of particle physics and may hint at new types of particles or interactions previously unknown to science, the team said. The researchers published their results in the journal Physical Review Letters.

"The radio waves that we detected were at really steep angles, like 30 degrees below the surface of the ice," said Stephanie Wissel, associate professor of physics, astronomy and astrophysics who worked on the ANITA team searching for signals from elusive particles called neutrinos. She explained that by their calculations, the anomalous signal had to pass through and interact with thousands of kilometers of rock before reaching the detector, which should have left the radio signal undetectable because it would have been absorbed into the rock. "It's an interesting problem because we still don't actually have an explanation for what those anomalies are, but what we do know is that they're most likely not representing neutrinos," Wissel said.

Smart Tires Will Report On the Health of Roads In New Pilot Program (arstechnica.com) 29

An anonymous reader quotes a report from Ars Technica: Do you remember the Pirelli Cyber Tire? No, it's not an angular nightmare clad in stainless steel. Rather, it's a sensor-equipped tire that can inform the car it's fitted to what's happening, both with the tire itself and the road it's passing over. The technology has slowly been making its way into the real world, starting with rarified stuff like the McLaren Artura. Now, Pirelli is going to put some Cyber Tires to work for everybody, not just supercar drivers, in a new pilot program with the regional government of Apulia in Italy.

The Cyber Tire has a sensor to monitor temperature and pressure, using Bluetooth Low Energy to communicate with the car. The electronics are able to withstand more than 3,500 G as part of life on the road, and a 0.3-oz (10 g) battery keeps everything running for the life of the tire. The idea was to develop a better tire pressure monitoring system, one that could tell the car exactly what kind of tire -- summer, winter, all-season, and so on -- was fitted, and even its state of wear, allowing the car to adapt its settings appropriately. But other applications suggested themselves -- at a recent CES, Pirelli showed how a Cyber Tire could warn other road users about aquaplaning. Then again, we've been waiting more than a decade for vehicle-to-vehicle communication to make a difference in daily driving to no avail.

Apulia's program does not rely on crowdsourcing data from Cyber Tires fitted to private vehicles. Regardless of the privacy implications, the rubber isn't nearly in widespread enough use for there to be a sufficient population of Cyber Tire-shod cars in the region. Instead, Pirelli will fit the tires to a fleet of vehicles supplied by the fleet management and rental company Ayvens. Driving around, the sensors in the tires will be able to infer how rough or irregular the asphalt is, via some clever algorithms. That's only one part of it, however. Pirelli and Apulia are also combining input from the tires with data from a network of road cameras and some technology from the Swedish startup Univrses. As you might expect, this data is combined in the cloud, and dashboards are available to enable end users to explore the data.

IBM Says It's Cracked Quantum Error Correction (ieee.org) 26

Edd Gent reporting for IEEE Spectrum: IBM has unveiled a new quantum computing architecture it says will slash the number of qubits required for error correction. The advance will underpin its goal of building a large-scale, fault-tolerant quantum computer, called Starling, that will be available to customers by 2029. Because of the inherent unreliability of the qubits (the quantum equivalent of bits) that quantum computers are built from, error correction will be crucial for building reliable, large-scale devices. Error-correction approaches spread each unit of information across many physical qubits to create "logical qubits." This provides redundancy against errors in individual physical qubits.

One of the most popular approaches is known as a surface code, which requires roughly 1,000 physical qubits to make up one logical qubit. This was the approach IBM focused on initially, but the company eventually realized that creating the hardware to support it was an "engineering pipe dream," Jay Gambetta, the vice president of IBM Quantum, said in a press briefing. Around 2019, the company began to investigate alternatives. In a paper published in Nature last year, IBM researchers outlined a new error-correction scheme called quantum low-density parity check (qLDPC) codes that would require roughly one-tenth of the number of qubits that surface codes need. Now, the company has unveiled a new quantum-computing architecture that can realize this new approach.
"We've cracked the code to quantum error correction and it's our plan to build the first large-scale, fault-tolerant quantum computer," said Gambetta, who is also an IBM Fellow. "We feel confident it is now a question of engineering to build these machines, rather than science."
