Research on Reconciliation Algorithm in Quantum Key Distribution

The quantum cryptography is an emerging technology, which uses quantum mechanics properties of micro-particles to encode information. In the theory and practice, it has been proved to be totally safe. Because of quantum channel being susceptible to be interfered by noise, error correction in quantum communication is facing a big problem today. This article will focus on cyclic redundancy check (CRC) replacing parity check in the protocol binary mainly in order to improve the efficiency of error correction and reduce the frequency of communication. And then its performance will be contrasted with the protocol binary with parity check by the self-designed simulation platform. The result shows that protocol binary with CRC can improve efficiency by up to around 50%.
