Analysis on the Bit Error Rate Distribution of Eavesdropping Detection and the Minimum Bits for Error Detection in a QKD system
Abstract— The precise estimation of quantum bit error rate is the base of the eavesdropping detection and data coordination in a quantum key distribution(QKD) protocol. Find that the sample bit-error-rate(BER) obeys the geometric distribution, obtain the relationship between BER, BER fluctuation, reliability and the minimum bits for error detection, get the minimum bits in a QKD When the reliability is given. Results show that with fixed reliability and the total amount of the raw keys reaching the given amount, the minimum bits for error detection is only related to BER and BER fluctuation, and has nothing to do with the total amount of raw keys.
Index Terms— QBER, BER fluctuation, reliability, geometric distribution, raw keys, minimum bits for error detection
