Google moves toward quantum supremacy with 72-qubit computer
IBM and Intel recently debuted similarly sized chips
LOS ANGELES — Quantum computers are bulking up.
Researchers from Google are testing a quantum computer with 72 quantum bits, or qubits, scientists reported March 5 at a meeting of the American Physical Society — a big step up from the company’s previous nine-qubit chip.
The team hopes to use the larger quantum chip to demonstrate quantum supremacy for the first time, performing a calculation that is impossible with traditional computers (SN: 7/8/17, p. 28), Google physicist Julian Kelly reported.
