The method of quantum optical communication based on entangled photon pairs

Abstract

During the last two decades have been successfully developed the quantum cryptography techniques that rely either on manipulation of the polarized single photons or the entangled photon pairs. At that has been found confirmation the fact the quantum correlations between the entangled photons are nearly or totally instantaneous but those correlations cannot be used for the direct superluminal information transfer as the state of the photon in the pair is unknown before the first measurement. Technology of entangled photons has made possible the modified double slit experiments where the appearance of the interference picture in detecting of the “signal” photons may be controlled by the manipulation of the spatially separated “idle” photons. In the present paper we discuss the possible superfast communication channel between the entanglement-linked distant parties using the remote manipulation of the interference picture formed statistically by the number of signal photons.
