在量子密码学中使用的一类人工构造的混合态对于信号的表示至关重要。这种对应关系表明，平方根测量给出了这类混合态的最佳测量。
A certain class of mixed states artificially constructed that is used in quantum cryptography is crucial for representation of signals. This correspondence shows that the square-root measurement gives the optimal measurement for such a class of mixed states.
