与纯粹的经典通信不同，如果Alice和Bob都配备了量子硬件，则无条件安全的密钥分发是可能的。协议需要量子化的程度不仅是一个有趣的理论问题，而且对实际实现也很重要。实际上，人们可能希望构造更便宜的设备，或者补偿设备故障。从这个意义上说，研究有限资源的QKD协议是一个重要的问题。研究这一问题的一个方向是Boyer等人在2007年引入的半量子模型（PRL 99 140501）。提出了几个可证明安全的半量子协议。然而，这些协议中的大多数在完美量子比特场景中被证明是安全的，不一定能抵御实际攻击。直到最近，从Boyer、Katz、利斯和莫尔在（PRA 96 062335）中的开创性工作开始，半量子密码学领域的研究才考虑到实际设备和不完善之处，例如多光子源和不完善的检测器。在这项工作中，我们提出了一个新的SQKD协议的基础上扩展的B92协议，它能够抵御某些实际的攻击。此外，我们使用的技术可能会广泛应用于其他有限资源（S）QKD协议。
Unlike purely classical communication, unconditionally secure key distribution is possible if Alice and Bob are both equipped with quantum hardware. The degree to which a protocol needs to be quantum is not only an interesting theoretical question, but also important for practical implementations. Indeed, one may wish to construct cheaper devices, or compensate for device malfunction. In this sense, studying limited resource QKD protocols is an important problem. One direction to studying this is the semi-quantum model introduced by Boyer et al. in 2007 (PRL 99 140501). Several provably secure semi-quantum protocols were put forth. However, most of these protocols were proven secure in the perfect qubit scenario and not necessarily against practical attacks. Only recently, starting with seminal work of Boyer, Katz, Liss, and Mor in (PRA 96 062335) has research in the field of semi-quantum cryptography considered practical devices and imperfections, such as multi photon sources and imperfect detectors. In this work, we present a new SQKD protocol based on an Extended B92 protocol which is able to counter certain practical attacks. Furthermore, the techniques we use may see broad application to other limited-resource (S)QKD protocols.
