Anti-butterfly effect enables new benchmarking of quantum-computer performance: Running a quantum system backward, then forward in time distinguishes information leaks from the desired information scrambling
Research drawing on the quantum “anti-butterfly effect” solves a longstanding experimental problem in physics and establishes a method for benchmarking the performance of quantum computers. “Using the simple, robust protocol we developed, we can determine the degree to which quantum computers can effectively process information, and it applies to information loss in other complex quantum […]
