Verifying analog quantum simulators beyond classical reach
Analog quantum simulators copy one physical system with another, without error correction. Once they outrun classical computers, a method is needed to tell whether their answers are right.
Why it matters
Without verification, claims of quantum advantage in simulation cannot be accepted or refuted.
