Shengmei Zhao · Computer Engineering and Applications Journal · 2008
Considering noise in the quantum channel of BB84 quantum key distribution protocol,an improved model of BB84 protocol with quantum error correction code,such as Quantum Low Density Parity Check code(QLDPC) is proposed in this paper.By numerical simulation,the effect of quantum error correction code on BB84 protocol is analyzed in the case of the efficiency of transmission rate.The results show that quantum LDPC codes have good ability to overcome the noise,raise the efficiency of transmission rate and verify the availability of the improved model.
