Abstract
A system and method of implementing quantum key distribution are provided that possess increased data rates and enhanced security. These increased data rates are provided through the use of biphotons. Through encoding bits of information on the intra-biphoton delay time and enabling separate polarization bases for each of the photons comprising each biphoton, the system and method increase data bandwidth available for quantum key distribution.
