Abstract

Quantum Key Distribution (QKD) is a promising technique to distribute unconditional secure keys for the remote two parties. In order to improve the final secure key rate of a QKD system, the Quantum Bit Error Rate (QBER) needs to be estimated as accurate as possible with minimum information leakage. In this paper, an improved parity-based error estimation scheme is proposed. The core part of the scheme is the proposed optimal block length calculation method. Simulation results show that the proposed scheme improves the accuracy of QBER estimation with less information leakage.
