单位信道上量子密钥分发协议的最优轴补偿
Optimal Axis Compensation in Quantum Key Distribution Protocols over Unital Channels
摘要：
轴补偿是发送器和接收器补偿其发送器和检测器的轴的过程，使得比特序列可以更可靠地传输。我们显示了最佳轴补偿最大化单位信道的密钥生成速率。我们考虑的情况下，只有鲍勃被允许补偿他的轴，并在其中的情况下，爱丽丝和鲍勃都被允许补偿他们的轴。在前一种情况下，我们表明，我们应该利用不匹配的测量结果在信道估计阶段。在后一种情况下，我们表明，我们不必利用不匹配的测量结果在信道估计阶段。
英文摘要：
The axis compensation is a procedure in which the sender and the receiver compensate the axes of their transmitter and detector so that the bit sequence can be transmitted more reliably. We show the optimal axis compensations maximizing the key generation rate for unital channels. We consider the case in which only Bob is allowed to compensate his axis, and the case in which both Alice and Bob are allowed to compensate their axes. In the former case, we show that we should utilize the mismatched measurement outcomes in the channel estimation phase. In the latter case, we show that we do not have to utilize the mismatched measurement outcomes in the channel estimation phase.
