Quantum advantage demo (Sycamore)
A quantum chip beats classical supercomputers on one task.
Google's 53-qubit Sycamore processor sampled random circuits in 200 seconds, a task it estimated would take a supercomputer 10,000 years. The claim was contested, but it marked a milestone for quantum hardware.
