| 摘 要： | 量子密钥分配协议具有可证明的绝对安全性,但是由于量子信道噪声的作用,量子比特在传输过程中容易产生错误,从而降低量子密钥分配的效率.对此,根据量子纠错理论,利用Hamming码构造一种[7,1]CSS纠错码,并结合BB84协议,提出一种改进的量子密钥分配协议.通过理论分析与数值计算,对比改进协议与BB84协议在含噪声量子...

| Abstract: | The quantum key distribution protocol has provable absolute security and plays an important role in the field of communication security.However,due to the effect of quantum channel noise,qubits are prone to errors during transmission,thereby reducing the efficiency of quantum key distribution.In this paper,according to the theory of quantum error correction,a[7,1]CSS error correction code is constructed by using Hamming code,and an improved quantum key distribution protocol is proposed based on BB84 protocol.Through theoretical analysis and numerical calculation,the transmission error rate of the improved protocol and BB84 protocol in the noisy quantum channel was compared.The results show that the improved quantum key distribution protocol improves the resistance to channel noise compared to the BB84 protocol. |
