Recently, quantum computing experiments have for the first time exceeded the
capability of classical computers to perform certain computations -- a
milestone termed "quantum computational advantage." However, verifying the
output of the quantum device in these experiments required extremely large
classical computations. An exciting next step for demonstrating quantum
capability would be to implement tests of quantum computational advantage with
efficient classical verification, such that larger system sizes can be tested
and verified. One of the first proposals for an …
