Breakthrough quantum computer could solve problems 200 times faster than a supercomputerScientists have built a compact physical qubit with built-in error correction, and now say it could be scaled into a 1,000-qubit machine that is small enough to fit inside a data center. They plan to release this machine in 2031.
