| Abstract(in English) | Quantum Key Distribution (QKD) has been attracting attention as an important technique to share a provably secure key under the existence of an eavesdropper. However, a security claim has been made repeatedly since 2009 that trace distance, a security parameter in QKD, is not interpreted correctly. The previous study pointed out that the interpretation was based on the misuse of coupling lemma. In this time, it is explained that trace distance appears only in Helstrom's quantum binary detection theory. |
