Abstract

An authorized user receiving bunched photon states from the output of a hyper-entangled photon server can make use on average of one fourth of the total transmitted events to gain situational awareness of the communications channel. Another user receiving bunched states can do the same. Both users then gain greater situational awareness on the confidentiality and integrity of the remaining half of the total transmission events wherein they both perform non-local correlated measurements on anti-bunched photon states. Keyed communication in quantum noise¹ (KCQ) is used to enhance confidentiality and efficiency. This depiction forms a baseline for more realistic models; all optical elements are perfect and propagation through channels is noiseless.
