Bound on measurement based on no-signaling

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Quantum mechanics implies the no-signaling condition: No local operation on one quantum system may affect the results of a local measurement on another quantum system, even if the two systems are entangled. This may be used to obtain bounds on quantum operations. As an example, we obtain a tight bound on the measurement which discriminates without error between two non-orthogonal states, without explicit reference to generalized measurements (POM strategies).
