 In its own heady blog post, Google debuted Willow, its latest quantum chip. It was flanked by hyped headlines that suggest something akin to the obelisk in 2001: A Space Odyssey. The breakthrough might not be about the power, however: Google says it has reduced errors — a major issue with building quantum computers — by adding more qubits to the system.
In fact, Google makes no claim of quantum supremacy this time — something the company did when it publicly debuted its previous generation quantum computer in 2019. That claim quickly ended in controversy, with one researcher calling the company's announcement "just plain wrong."
Part of the issue then was that Google's last quantum chip was not part of a general-purpose quantum computer. Instead, it surpassed classic computers in a single task: random circuit sampling (RCS). But, in Google's own words, RCS has "no known real-world applications."

However, the company is sticking with the metric, claiming RCS performance is a widely recognized gauge of quantum computing. That makes true comparisons difficult: Rivals including IBM and Honeywell use a quantum volume metric to tout their brea

Google debuted Willow, its latest quantum chip, on Wednesday, and if you've spent any time online since, you've undoubtedly run into some breathless reporting about it. Willow "crushes classical computers on a cosmic timescale," proclaims one headline; Google "unveils ‘mind-boggling' quantum computer chip," reads another. It's all anchored by a claim that Willow can complete a computation that would theoretically take a classical computer significantly more time than the 14 billion years the universe has existed. But, as you can probably guess, what the chip represents is not so simple.
First, with Willow, Google makes no claim of quantum supremacy, something the company did when it publicly debuted its previous generation quantum computer, Sycamore, back in 2019. You may recall that, at the time, Google publicized how it took Sycamore just 200 seconds to perform a calculation that would have theoretically taken the world's then-fastest supercomputer 10,000 years to complete. That feat, the company said, demonstrated that it had created a quantum computer that could solve problems the best classical computers could not even attempt. In other words, Google had achieved quantum supremacy.

NVIDIA, graphics chip maker and recent backbone of the AI industry, is under investigation by Chinese regulators over potential antitrust violations, The New York Times reports. The concerns center on the acquisition of Mellanox Technologies, a computer networking company NVIDIA bought in 2020.
As part of the conditions of that acquisition, Chinese regulators required NVIDIA to "provide information about new [Mellanox] products to rivals within 90 days of making them available to NVIDIA," Bloomberg writes. China's State Administration for Market Regulation is kicking off its investigation because it believes that those terms were violated. This wouldn't be the first time NVIDIA has been investigated for monopolistic behavior - The US Department of Justice reportedly launched
