在量子密钥分配的后处理中,来自失配基测量的原始密钥比特通常被丢弃,其中双方使用不同的基。在这里,我们提出了一种后处理方法,利用测量统计不匹配的基础情况下,并证明,将这些统计数据,使uncharacterized量子比特源中使用的测量设备无关的量子密钥分配协议和Bennett-Bennard 1984协议,否则是不可能的情况下。
In the postprocessing of quantum key distribution, the raw key bits from the mismatched-basis measurements, where two parties use different bases, are normally discarded. Here, we propose a postprocessing method that exploits measurement statistics from mismatched-basis cases, and prove that incorporating these statistics enables uncharacterized qubit sources to be used in the measurement-device-independent quantum key distribution protocol and the Bennett-Brassard 1984 protocol, a case which is otherwise impossible.
