摘要: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 eta = 100% in theory. (C) 2009 Elsevier B.V. All rights reserved.
