Abstract

Quantum secure direct communication (QSDC) can transmit the secret message directly. Single-photon-based QSDC protocol requires the active modulation of the quantum state of the source, potentially introducing various side-channel vulnerabilities. In this paper, we propose a passive-state preparation QSDC protocol. By utilizing a passive-state preparation method, we remove the need for active modulation, thus eliminating the side-channel risks associated with the source encoder. To evaluate the performance of the protocol, we develop a system model and improve the decoy state method. Through parameter optimization, we identify the optimal secrecy message capacity for various communication distances and compare it with active modulation QSDC. At a communication distance of 10 (15) km, the secrecy message capacity of passive-state preparation QSDC reaches 3.894 × 10−4 (3.715 × 10−5) bit/pulse, achieving 95.3% (91.5%) of the active case’s performance. Meanwhile, we consider the resource consumption and optimize the secrecy message transmission rate of passive-state preparation QSDC. Using a coherent light source with a frequency of 106 Hz, at communication distances of 5, 10, and 15 km, the secrecy message transmission rates for passive-state preparation QSDC reach 2.370 × 102, 4.218 × 10, and 2.504 bit/s, respectively.

量子安全直接通信的无源状态制备
量子安全直接通信(QSDC)可以直接传输秘密信息。基于单光子的QSDC协议需要对源的量子态进行有源调制,这可能会引入各种侧信道漏洞。在本文中,我们提出了一种被动状态准备QSDC协议。通过利用无源状态制备方法,我们消除了有源调制的需要,从而消除了与源编码器相关的侧信道风险。为了评估协议的性能,我们建立了一个系统模型并改进了诱饵状态方法。通过参数优化,确定了不同通信距离下的最优保密报文容量,并与有源调制QSDC进行了比较。在通信距离为10 (15)km时,被动状态制备QSDC的保密报文容量达到3.894 × 10−4 (3.715 × 10−5)bit/pulse,达到主动状态性能的95.3%(91.5%)。同时,考虑了被动状态准备QSDC的资源消耗,优化了保密消息传输速率。使用频率为106 Hz的相干光源,在通信距离为5、10和15 km时,被动状态制备QSDC的保密消息传输速率分别达到2.370 × 102、4.218 × 10和2.504 bit/s。
