通过找到最佳解决相邻量子态的测量，我们使用统计可扩展性来定义量子力学密度算符空间上的自然黎曼度量，并制定比标准不确定性原理更普遍和更严格的不确定性原理。
By finding measurements that optimally resolve neighboring quantum states, we use statistical distinguishability to define a natural Riemannian metric on the space of quantum-mechanical density operators and to formulate uncertainty principles that are more general and more stringent than standard uncertainty principles.
