A novel quantum key distribution scheme with orthogonal product states
Guo-Ping Guo, Chuan-Feng Li, Bao-Sen Shi, Jian Li, Guang-Can Guo
abstract: The general conditions for the orthogonal product states of the multi-state
systems to be used in quantum key distribution (QKD) are proposed, and a novel
QKD scheme with orthogonal product states in the 3x3 Hilbert space is
presented. We show that this protocol has many distinct features such as great
capacity, high efficiency. The generalization to nxn systems is also discussed
and a fancy limitation for the eavesdropper's success probability is reached.
