Single-shot comparison of random quantum channels and measurements

Quantum Physics 2025-12-01 v2

Abstract

In this work we provide an efficiency analysis of the problem of comparison of two randomly chosen quantum operations in the single-shot regime. We provide tight bounds for the success probability of such a protocol for arbitrary quantum channels and generalized measurements.
