原子量子计算机实现纠错里程碑

Quantum computing An error-correction milestone An atom-based quantum computer can correct its own errors during long computations, an important prerequisite for becoming truly useful, reports Karmela Padavic-Callaghan THE race to build the first truly useful quantum computer just got more exciting. A quantum computer made from extremely cold atoms has now passed some of the most important milestones towards usefulness, joining a small group of equally able and promising machines. the new work makes a case for being able to do both. “This study is the first to bring together all of the capabilities needed to build a real neutral-atom quantum computer in a single experiment,” says Jeff Thompson at Princeton University. …
