2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/90989We discuss the problem of when a set of measurements made on an entangled source can be simulated with a classically correlated source. This is discussed in general and some examples are given. The question of which aspects of quantum imaging can be simulated by classically correlated sources is examined.Quantum Physicstext
