Modified Bennett-Brassard 1984 Quantum Key Distribution With Two-way Classical Communications

Quantum Physics 2009-11-11 v1

Abstract

The quantum key distribution protocol without public announcement of bases is equipped with a two-way classical communication symmetric entanglement purification protocol. This modified key distribution protocol is unconditionally secure and has a higher tolerable error rate of 20%, which is higher than previous scheme without public announcement of bases.
