Protocol for Communication via Differentiation of Hidden Basis from Linear Basis of Entangled Photon Pair Polarization

Authors: Wells M Chandler

What is the polarization basis of an entangled photon pair when exiting a beta-barium borate crystal (BBO)? Repeated experiments have confirmed there is no linear polarization basis that can account for the observed (anti-)correlations of the pair. Rather, the pair is initially defined by a real but inaccessible basis of polarization which is orthogonal to all linear polarization bases — a hidden basis[1]. The properties of orthogonality of the hidden basis to all linear polarization bases and the instantaneous decoherence of both members of the pair to a linear polarization basis following measurement of one member are exploited in the following experimental proposal to facilitate limited faster than light communication.
