Quantum cryptography with floating basis protocol

摘要

A new Quantum cryptography protocols with several bases and infinite number of bases is proposed. This work considers with the idea of enlarging number of bases. The first part of the work presents an experimental realization of two, three and six bases protocols. Then principle of enlarging of the bases number leads to the infinite number of bases or to the floating basis protocol. This protocol requires existence of some secret key. This key helps to make Alice's and Bob's bases coincide. So the transmission becomes twice faster and restricts of the mean photon number becomes lower.
