Google’s quantum supremacy is only a first taste of a computing revolution “Quantum supremacy” is nice, but more broadly useful quantum computers are probably still a decade away.

A Google quantum computer has far outpaced ordinary computing technology, an achievement called quantum supremacy that’s an important milestone for a revolutionary way of processing data. Google disclosed the results in the journal Nature on Wednesday. The achievement came after more than a decade of work at Google, including the use of its own quantum computing chip, called Sycamore.…
