Measurement-device-independent quantum key distribution (MDIQKD) is a revolutionary protocol since it is physically immune to all attacks on the detection side. However, the protocol still keeps the strict assumptions on the source side that specify that the four BB84 states must be perfectly prepared to ensure security. Some protocols release part of the assumptions in the encoding system to keep the practical security, but the performance would be dramatically reduced. In this work, we present a MDIQKD protocol that requires less knowledge of the encoding system to combat the troublesome modulation errors and fluctuations. We have also experimentally demonstrated the protocol. The result indicates a high performance and good security for practical applications. Its robustness and flexibility also exhibit a good value for complex scenarios such as the QKD networks.

与测量设备无关的量子密钥分发 (MDIQKD) 是一种革命性的协议，因为它在物理上不受检测端的所有攻击的影响。但是，该协议仍然在源端保持严格的假设，即必须完全准备好四个 BB84 状态以确保安全。一些协议在编码系统中释放了部分假设以保持实际的安全性，但性能会大大降低。在这项工作中，我们提出了一种 MDIQKD 协议，该协议需要较少的编码系统知识来应对麻烦的调制错误和波动。我们还通过实验证明了该协议。结果表明在实际应用中具有高性能和良好的安全性。
