Abstract
A method is provided for distributing quantum cryptographic keys. The method includes receiving a first quantum signal from an initial quantum key generating transmitter. Following correspondence with the initial quantum key generating transmitter, a first quantum key is generated. A second quantum signal is transmitted to a recipient quantum key generating transmitter. Following correspondence with the recipient quantum key generating receiver, a second quantum key is generated. The first quantum key is encoded using the second quantum key. The encoded first quantum key is transmitted to the recipient quantum key generating receiver using the second quantum key.
