QUANTUM KEY distribution - the use of quantum properties to exchange secret information, such as a cryptographic key, which can then be used to encrypt messages that are being communicated over an insecure channel - is a specialised science conducted by the NASA Glenn Research Center at Cleveland, Ohio. As part of its broader research efforts, NASA Glenn is currently testing a device to detect laser and photon communication frequencies as the foundation of a quantum key distribution system. Fitted to the underside fuselage of NASA Glenn's 1966 model De Havilland Canada DHC-6 Twin Otter, N607NA (c 4), the detection device is being flight tested for use on unmanned aircraft.
