A linear optical protocol of random quantum key distribution by using polarization entangled photons

Utilized polarization entangled photons, a linear optical protocol for generating random quantum key distribution (QKD) is proposed, which is made up of EPR-source, linear optical elements, and conventional photon detectors. It is shown that total efficiency of QKD η = 100 % in theory.
