用Weyl-Winger对应求证相干态的一个重要性质
Weyl-Winger Correspondence for Proving an Important Nature of the Coherent State
摘要
一般而言,一个量子算符只有其在某个表象中所有的矩阵元都知道了才能被确定。可是当一个量子算符的相干态平均值(对角表示)知道了,这个算符本身就确定了,这是一个值得注记的性质。本文用Weyl-Winger对应的唯一性证明这一性质。
Abstract
Generally speaking,a quantum operator can be identified only when all of its matrix elements in some representation are known.However,when a quantum operator's coherent state average value (diagonal elements) is known,this operator itself is determined.This is a character worthy to be noted.In this paper,we use the uniqueness Weyl-Winger correspondence to prove this character.
