累积量和矩代数:分析弱测量的工具

Cumulants and the moment algebra: tools for analysing weak measurements

Johan Aberg, Graeme Mitchison

摘要:

最近,它已被证明,累积量显着简化了分析的多部弱测量。在这里,我们考虑的数学结构的基础上,这一点,并发现它可以制定在我们所谓的时刻代数。除了导致在更简单的证明,这种结构的灵活性,允许推广的原始结果的一些弱测量方案,包括一个弱相互作用的指针达到热平衡与探测系统。

英文摘要:

Recently it has been shown that cumulants significantly simplify the analysis of multipartite weak measurements. Here we consider the mathematical structure that underlies this, and find that it can be formulated in terms of what we call the moment algebra. Apart from resulting in simpler proofs, the flexibility of this structure allows generalizations of the original results to a number of weak measurement scenarios, including one where the weakly interacting pointers reach thermal equilibrium with the probed system.
