Apparatus and Method for Quantum Mechanical Encryption for the Transmission of Secure Communications

Reference#: P00452


An apparatus and method were developed that permit the transmission of secure communications. The invention uses quantum mechanical effects to establish nonlocal correlations between a pair of photons. This is analogous to an automatic encryption code that exists at only one location and is immediately destroyed after either of the photons is detected. This latter feature also provides a means for detecting any unauthorized tap on the transmission line.
