A SYSTEM AND METHOD FOR QUANTUM KEY DISTRIBUTION WITH ENTANGLED PHOTON PAIRS.

摘要

The present invention relates to a system and a method for entanglement-based quantum key distribution (QKD), wherein photons used for quantification of security and forming of the raw key can be reallocated and wasted photons' information may be recycled. Accordingly, the present invention provides a system for quantum key distribution comprising a photon source configured to generate entangled photon pair comprising first and second photon and two receiving units configured to receive separately first and second photon.
