Defeating passive eavesdropping with quantum illumination

A two-way protocol for defeating passive eavesdropping is proposed. For each information bit, Alice sends Bob T sec of signal-beam output from a spontaneous parametric down-converter over a pure-loss channel while retaining the idler beam with which it is maximally entangled. Bob imposes a single in...
