文章采用密度算符间的距离充分率证了双光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型在初始相干光场较强时（ｎ≥１）在某些特定时刻（ｇｔ＝（２ｍ＋１）π／４，ｍ＝０，１，２，．．．）腔场演化为振幅相同而位相差为π／２或３π／２的两个相干态的叠加态，即Ｓｃｈｒｏｅｄｉｎｇｅｒ－Ｃａｔ态，给出了Ｓｃｈｒｏｅｄｉｎｇｅｒ－Ｃａｔ态的演化图象。

E. T. Jaynes

One of the most successful physicists of the generation immediately before Hugh Everett III, E. T. Jaynes shared both Everett's interest in applications of information theory to physics and his foundational orientation. But whereas Everett focused on quantum mechanics, much of Jaynes' work concerned how to use information theory in thermodynamics. This document is a single page from Jaynes' paper "Information Theory and Statistical Mechanics," Physical Review, 106, 620-630 (1957). Based on the basic content of his penciled observations, Everett wrote to Jaynes with an analysis of the flaws in Jaynes paper. He enclosed a copy of his own relative states preprint. Jaynes wrote back at great length.
