So, the paper describes how some logical operations can be performed relatively easily, while a few others require manipulations of the error correction scheme in order to work. (These manipulations have names like lattice surgery and magic state distillation, which are good signs that the field doesn’t take itself that seriously.) So, in sum, Microsoft ..

Some of the sediment layers contained the remains of ancient grass seeds mixed with the sediment. Bennett and his colleagues radiocarbon-dated seeds from the layer just below the oldest footprints and the layer just above the most recent ones. According to those 2021 results, the oldest footprints were made sometime after 23,000 years ago; the ..
Earlier this year, a biomedical researcher at the University of Michigan received an update from the National Institutes of Health. The federal agency, which funds a large swath of the country’s medical science, had given the green light to begin releasing funding for the upcoming year on the researcher’s multi-year grant. Not long after, the ..
The blackout that took down the Iberian grid serving Spain and Portugal in April was the result of a number of smaller interacting problems, according to an investigation by the Spanish government. The report concludes that several steps meant to address a small instability made matters worse, eventually leading to a self-reinforcing cascade where high ..
“I understood that this was her basic nature, and she had a lot to lose, but I didn’t like it,” said O’Shaughnessy, although love ultimately triumphed. “I wish we could have been more open. I loved her. It would have been fun to share her more, even with some of her friends that she wouldn’t ..

SpaceX tries something new with Falcon 9. With nearly 500 launches under its belt, SpaceX’s Falcon 9 rocket isn’t often up to new tricks. But the company tried something new following a launch on June 7 with a radio broadcasting satellite for SiriusXM. The Falcon 9’s upper stage placed the SXM-10 satellite into an elongated, high-altitude ..
Robots like Atlas, Spot, and Stretch have amazed people with natural, life-like agility and body balance. What they were lacking, though, was a way to quickly connect this natural movement to perception—the robotic equivalent of the reflexes that let you catch a ball or duck in an instant to avoid getting hit. So, a team ..
If signed into law as written, the White House’s proposal to slash nearly 25 percent from NASA’s budget would have some dire consequences. It would cut the agency’s budget from $24.8 billion to $18.8 billion. Adjusted for inflation, this would be the smallest NASA budget since 1961, when the first American launched into space. The proposed funding plan ..
A critical measure of the ocean’s health suggests that the world’s marine systems are in greater peril than scientists had previously realized and that parts of the ocean have already reached dangerous tipping points. A study, published Monday in the journal Global Change Biology, found that ocean acidification—the process in which the world’s oceans absorb ..
