Claim:
1. A method for creating correlated polarization measurements of photons at distinct locations, comprising the steps of: rotating the phase of those photons in a polarization entangled photon pair having incongruent frequencies; directing said polarization entangled photon pair into a first beam splitter; passing those photons having a polarization aligned with a first beam splitter and reflecting in an orthogonal direction those photons having a polarization not aligned with said first beam splitter; rotating the phase of: directing said passed and said orthogonally directed photons into a second beam splitter; passing those photons having a polarization aligned with said second beam splitter and reflecting in an orthogonal direction those photons having a polarization not aligned with said second beam splitter; and measuring the polarization of said photons exiting said second beam splitter.
