Google observes noise-driven phases in random-circuit sampling

Apr 21, 2023

Alexis Morvan and colleagues report distinct regimes in random-circuit sampling as noise competes with quantum dynamics. Their experiments and analysis connect these transitions to the difficulty of reproducing the results classically.

Why it matters

Sampling benchmarks need evidence that noise has not made their outputs easy to imitate; qubit count alone does not establish a computational advantage.
