Claim of quantum supremacy reported

摘要

A leaked paper suggests that Google has achieved a milestone known as quantum supremacy, using a quantum computer to perform a calculation that couldn't be achieved even with the world's most powerful supercomputers.It's a hotly anticipated goal, and one intended to mark the beginning of a new era of quantum computation (SN: 7/8/17& 7/22/17, p. 28). But it's also largely symbolic: The calculation in question serves little practical purpose and is designed to be difficult for standard computers that are not rooted in quantum physics.
