量子熵最基本的属性是通过考虑两个系综的并集得出的。我们讨论了这些属性对熵度量的限制，并发现它们唯一地确定了归一化之前的熵函数的形式。特别是，该结果意味着量子熵的所有其他性质都可以从这些第一原理推导出来。
The most fundamental properties of quantum entropy are derived by considering the union of two ensembles. We discuss the limits these properties put on an entropy measure and obtain that they uniquely determine the form of the entropy functional up to normalisation. In particular, the result implies that all other properties of quantum entropy may be derived from these first principles.
