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."

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.

NASA and Axiom Space have indefinitely delayed the Axiom-4 launch to the International Space Station due to concerns about a persistent air leak in the Russian PrK vestibule of the aging Zvezda module. "The PrK serves as a passageway between the station's Zvezda module and spacecraft docked at its aft port," notes CBS News. From the report: In a blog post, NASA said cosmonauts aboard the station "recently performed inspections of the pressurized module's interior surfaces, sealed some additional areas of interest, and measured the current leak rate. Following this effort, the segment now is holding pressure." The post went on to say the Axiom-4 delay will provide "additional time for NASA and (the Russian space agency) Roscosmos to evaluate the situation and determine whether any additional troubleshooting is necessary."

Launched in July 2000 atop a Russian Proton rocket, Zvezda was the third module to join the growing space station, providing a command center for Russian cosmonauts, crew quarters, the aft docking port and two additional ports now occupied by airlock and research modules. The leakage was first noticed in 2019, and has been openly discussed ever since by NASA during periodic reviews and space station news briefings. The leak rate has varied, but has stayed in the neighborhood of around 1-to-2 pounds per day. "The station is not young," astronaut Mike Barratt said last November during a post flight news conference. "It's been up there for quite a while, and you expect some wear and tear, and we're seeing that in the form of some cracks that have formed." The Russians have made a variety of attempts to patch a suspect crack and other possible sources of leakage, but air has continued to escape into space.

In November, Bob Cabana, a former astronaut and NASA manager who chaired the agency's ISS Advisory Committee, said U.S. and Russian engineers "don't have a common understanding of what the likely root cause is, or the severity of the consequences of these leaks." "The Russian position is that the most probable cause of the PrK cracks is high cyclic fatigue caused by micro vibrations," Cabana said. "NASA believes the PrK cracks are likely multi-causal including pressure and mechanical stress, residual stress, material properties and environmental exposures. "The Russians believe that continued operations are safe, but they can't prove to our satisfaction that they are, and the US believes that it's not safe, but we can't prove that to the Russian satisfaction that that's the case."

As an interim step, the hatch leading to the PrK and the station's aft docking compartment is closed during daily operations and only opened when the Russians need to unload a visiting Progress cargo ship. And as an added precaution on NASA's part, whenever the hatch to the PrK and docking compartment is open, a hatch between the Russian and U.S. segments of the station is closed. "We've taken a very conservative approach to close a hatch between the US side and the Russian side during those time periods," Barratt said. "It's not a comfortable thing, but it is the best agreement between all the smart people on both sides. And it's something that we crew live with and enact." Cabana said last year that the Russians do not believe "catastrophic disintegration of the PrK is realistic (but) NASA has expressed concerns about the structural integrity of the PrK and the possibility of a catastrophic failure."

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.

An anonymous reader quotes a report from the Wall Street Journal: Since 2022, the U.S. has tightened the noose around the sale of high-end AI chips and other technology to China overnational-security concerns. Yet Chinese companies have made advances using workarounds. In some cases, Chinese AI developers have been able to substitute domestic chips for the American ones. Another workaround is to smuggle AI hardware into China through third countries. But people in the industry say that has become more difficult in recent months, in part because of U.S. pressure. That is pushing Chinese companies to try a further option: bringing their data outside China so they can use American AI chips in places such as Southeast Asia and the Middle East (source paywalled; alternative source). The maneuvers are testing the limits of U.S. restrictions. "This was something we were consistently concerned about," said Thea Kendler, who was in charge of export controls at the Commerce Department in the Biden administration, referring to Chinese companies remotely accessing advanced American AI chips. Layers of intermediaries typically separate the Chinese users of American AI chips from the U.S. companies -- led by Nvidia -- that make them. That leaves it opaque whether anyone is violating U.S. rules or guidance. [...]

At the Chinese AI developer, the Malaysia game plans take months of preparation, say people involved in them. Engineers decided it would be fastest to fly physical hard drives with data into the country, since transferring huge volumes of data over the internet could take months. Before traveling, the company's engineers in China spent more than eight weeks optimizing the data sets and adjusting the AI training program, knowing it would be hard to make major tweaks once the data was out of the country. The Chinese engineers had turned to the same Malaysian data center last July, working through a Singaporean subsidiary. As Nvidia and its vendors began to conduct stricter audits on the end users of AI chips, the Chinese company was asked by the Malaysian data center late last year to work through a Malaysian entity, which the companies thought might trigger less scrutiny.

The Chinese company registered an entity in Kuala Lumpur, Malaysia's capital, listing three Malaysian citizens as directors and an offshore holding company as its parent, according to a corporate registry document. To avoid raising suspicions at Malaysian customs, the Chinese engineers packed their hard drives into four different suitcases. Last year, they traveled with the hard drives bundled into one piece of luggage. They returned to China recently with the results -- several hundred gigabytes of data, including model parameters that guide the AI system's output. The procedure, while cumbersome, avoided having to bring hardware such as chips or servers into China. That is getting more difficult because authorities in Southeast Asia are cracking down on transshipments through the region into China.

Last week Anthropic CEO Dario Amodei said AI could eliminate half the entry-level white-collar jobs within five years. CNN called the remarks "part of the AI hype machine."

Asked about the prediction this week at a Paris tech conference, NVIDIA CEO Jensen Huang acknowledged AI may impact some employees, but "dismissed" Amodei's claim, according to Fortune. "Everybody's jobs will be changed. Some jobs will be obsolete, but many jobs are going to be created ... Whenever companies are more productive, they hire more people."

And he also said he "pretty much" disagreed "with almost everything" Anthropic's CEO says.

"One, he believes that AI is so scary that only they should do it," Huang said of Amodei at a press briefing at Viva Technology in Paris. "Two, [he believes] that AI is so expensive, nobody else should do it ... And three, AI is so incredibly powerful that everyone will lose their jobs, which explains why they should be the only company building it. I think AI is a very important technology; we should build it and advance it safely and responsibly," Huang continued. "If you want things to be done safely and responsibly, you do it in the open ... Don't do it in a dark room and tell me it's safe."

An Anthropic spokesperson told Fortune in a statement: "Dario has never claimed that 'only Anthropic' can build safe and powerful AI. As the public record will show, Dario has advocated for a national transparency standard for AI developers (including Anthropic) so the public and policymakers are aware of the models' capabilities and risks and can prepare accordingly.
NVIDIA's CEO also touted their hybrid quantum-classical platformCUDA-Q and claimed quantum computing is hitting an "inflection point" and within a few years could start solving real-world problems

Earlier this week looters who stole iPhones "got an unexpected message from Apple," reports the Economic Times.

"Please return to Apple Tower Theatre. This device has been disabled and is being tracked. Local authorities will be alerted."

Stolen phones "were remotely locked and triggered alarms, effectively turning the devices into high-tech bait. Videos circulating online show the phones flashing the message while blaring loudly, making them impossible to ignore."

According to LAPD Officer Chris Miller, at least three suspects were apprehended in connection to the Apple Store burglary. One woman was arrested on the spot, while two others were detained for looting.

An anonymous reader shared this report from CNET:

By using a software emulator to run Atari's 1979 game Video Chess, Citrix engineer Robert Caruso said he was able to set up a match between ChatGPT and the 46-year-old game. The matchup did not go well for ChatGPT. "ChatGPT confused rooks for bishops, missed pawn forks and repeatedly lost track of where pieces were — first blaming the Atari icons as too abstract, then faring no better even after switching to standard chess notations," Caruso wrote in a LinkedIn post.
"It made enough blunders to get laughed out of a 3rd-grade chess club," Caruso said. "ChatGPT got absolutely wrecked at the beginner level."

"Caruso wrote that the 90-minute match continued badly and that the AI chatbot repeatedly requested that the match start over..." CNET reports.

"A representative for OpenAI did not immediately return a request for comment."
