Quantum computer bests all conventional computers in first claim of ‘supremacy’

by Adrian Cho, Science

The age of quantum computing may have begun not with a flashy press conference, but with an internet leak. According to a paper posted briefly—and presumably mistakenly—to a lab site, physicists at Google have used a quantum computer to perform a calculation that would overwhelm the world’s best conventional supercomputer. Although the specific computation has no known use, the result means scientists have passed a milestone known as “quantum supremacy.”

IBM’s new 53-qubit quantum computer is its biggest yet

by Stephen Shankland, C|NET

The system will go online in October.

IBM’s 14th quantum computer is its most powerful so far, a model with 53 of the qubits that form the fundamental data-processing element at the heart of the system. The system, available online to quantum computing customers in October, is a big step up from the last IBM Q machine with 20 qubits and should help advance the marriage of classical computers with the crazy realm of quantum physics.
