我们引入了一种新形式的诱骗态技术，使单光子班尼特1992协议对通信信道的损耗和噪声具有鲁棒性。发送端准备两个无信息状态，以防止无模糊状态鉴别攻击，提高相位误差率估计。所提出的方法不需要强参考脉冲，额外的电子设备或额外的检测器来实现。
We introduce a novel form of decoy-state technique to make the single-photon Bennett 1992 protocol robust against losses and noise of a communication channel. Two uninformative states are prepared by the transmitter in order to prevent the unambiguous state discrimination attack and improve the phase-error rate estimation. The presented method does not require strong reference pulses, additional electronics or extra detectors for its implementation.
