Abstract
A method and apparatus for forming and distributing quantum encryption keys. A first quantum signal generated by a number generator in a communicator is transmitted through an aperture in the communicator to a receiving communicator. A second quantum signal is received through the aperture at the communicator from a transmitting communicator. The first quantum signal is isolated from the second quantum signal such that the first quantum signal is transmitted from the communicator in response to the first quantum signal passing through the aperture and such that the second quantum signal is received at a number detector in the communicator in response to the second quantum signal passing through the aperture.
