Google claims experimental quantum advantage with Sycamore
Google’s 53-qubit processor performed a specialised random-circuit sampling task much faster than the classical estimate used by the team.
The experiment showed control of a programmable quantum processor beyond the team’s classical comparison for one contrived task. IBM disputed the original classical-runtime estimate, and the calculation had no direct commercial use. It was a laboratory milestone, not general quantum superiority.
