统计量子运算
Statistical quantum operation
摘要：
提出了一种通用的单位正算子值测度（POVM），它将一个给定的定态纯态变换为一个具有完全退相干的任意统计态。这使得我们可以在操作上实现热化作为一种特殊情况。通过计算熵，讨论了由于操作产生的随机性而导致的信息损失。作为一个说明性的例子，讨论了二分自旋-1/2系统的热化。
英文摘要：
A generic unital positive operator-valued measure (POVM), which transforms a given stationary pure state to an arbitrary statistical state with perfect decoherence, is presented. This allows one to operationally realize thermalization as a special case. The loss of information due to randomness generated by the operation is discussed by evaluating the entropy. Thermalization of the bipartite spin-1/2 system is discussed as an illustrative example.
