Realizes: quantum supremacy via random circuit sampling

A 53-qubit superconducting transmon processor built by Google AI Quantum that executed a random quantum circuit sampling task in 2019 to demonstrate quantum supremacy, providing empirical evidence of a computation outside the reach of classical supercomputers at the time.

Google Sycamore quantum supremacy experiment (2019)

Documented by Google AI Quantum and the 2019 Nature paper, the Sycamore processor sampled random circuits in roughly 200 seconds on 53 superconducting qubits, illustrating a computation believed to be prohibitive for classical machines at the time.
