Violation of no-Signaling Constraint by Distinguishing Local Quantum Measurement with Numerous Eight-Particle GHZ States

The distinction of quantum measurements is one of the fundamentally important problems in quantum information science. In this paper we present a novel protocol for distinguishing local quantum measurement (DLQM) with multi-particle entanglement systems. It is shown that, for two spacelike separated parties, the local discrimination of two different kinds of measurement can be completed via numerous eight-particle GHZ entangled states and selective projective measurements without help of classical information. This means that no-signaling constraint can be violated by the DLQM.
