Quantum Volume is a metric that determines how powerful a quantum computer is. It measures the length and complexity of quantum circuits, the building blocks of quantum applications.
Just two months ago, Honeywell similarly announced it had a quantum computer running client jobs with a Quantum Volume of 64. Honeywell reached the milestone with just a 6-qubit system.
IBM’s previous Quantum Volume milestone, announced in January, was 32. The company said it reached a Quantum Volume of 64 through a series of new software and hardware techniques applied to a system already deployed within the IBM Q Network. (ZDnet)
