Entanglement cost of discriminating noisy Bell states by local operations and classical communication
Somshubhro Bandyopadhyay, Vincent Russo
Entangled states can help in quantum state discrimination by local operations and classical communication (LOCC). For example, a Bell state is necessary (and sufficient) to perfect…
