论文摘要
量子安全直接通信（QSDC）使用量子通道可靠，安全地传输信息。为了消除实际检测器产生的安全漏洞，已经提出了测量设备独立的QSDC协议。但是，MDI-QSDC中使用了基于块的量子状态的传输，这需要在写作时仍无法使用的实用量子内存。为了避免这种障碍，我们提出了一个单光照MDI QSDC协议（SPMQC），用于用高性能量子记忆分配。所提出的协议的性能的特征是仿真考虑了现实的实验参数，结果表明，通过依靠当今的技术来实现SPMQC是可行的。
Quantum secure direct communication (QSDC) uses the quantum channel to transmit information reliably and securely. In order to eliminate the security loopholes resulting from practical detectors, the measurement-device-independent (MDI) QSDC protocol has been proposed. However, block-based transmission of quantum states is utilized in MDI-QSDC, which requires practical quantum memory that is still unavailable at the time of writing. For circumventing this impediment, we propose a single-photon-memory MDI QSDC protocol (SPMQC) for dispensing with high-performance quantum memory. The performance of the proposed protocol is characterized by simulations considering realistic experimental parameters, and the results show that it is feasible to implement SPMQC by relying on present-day technology.
