一类不完美量子密封协议的上界

Upper bounds of a class of imperfect quantum sealing protocols

Guang-Ping He

摘要:

研究了密封一个经典比特的量子协议模型。证明了其安全性存在上界。对于可以以概率$α$正确读取比特并且可以以概率$β$检测到读取比特的任何协议,上限是$% β\leqslant 1/2$和$α+β\leqslant 9/8$。

英文摘要:

The model of the quantum protocols sealing a classical bit is studied. It is shown that there exist upper bounds on its security. For any protocol where the bit can be read correctly with the probability $α$, and reading the bit can be detected with the probability $β$, the upper bounds are $% β\leqslant 1/2$ and $α+β\leqslant 9/8$.
