摘要:

本文给出了贝叶斯量子态分配方法在三能级量子系统中具体数值应用的例子。根据各种测量数据和各种先验知识的证据分配的统计算子部分地通过分析计算,部分地通过计算机上的数值积分(在八个维度中)计算。测量数据包括在绝对频率的N个相同的冯诺依曼投影测量的结果进行N个相同的准备三能级系统。各种小值的N以及大N的限制被认为是。使用两种先验知识:一种由关于统计算子集合的凸结构的可扩展性分布常数表示;另一种由以纯统计算子为中心的高斯分布表示,从而反映了一种情况,其中一种情况具有关于系统的可能准备的有用先验知识。在一个配套文件的情况下,测量数据组成的平均值,和额外的事先研究斯莱特,被认为是。

英文摘要:

This paper offers examples of concrete numerical applications of Bayesian quantum-state-assignment methods to a three-level quantum system. The statistical operator assigned on the evidence of various measurement data and kinds of prior knowledge is computed partly analytically, partly through numerical integration (in eight dimensions) on a computer. The measurement data consist in absolute frequencies of the outcomes of N identical von Neumann projective measurements performed on N identically prepared three-level systems. Various small values of N as well as the large-N limit are considered. Two kinds of prior knowledge are used: one represented by a plausibility distribution constant in respect of the convex structure of the set of statistical operators; the other represented by a Gaussian-like distribution centred on a pure statistical operator, and thus reflecting a situation in which one has useful prior knowledge about the likely preparation of the system. In a companion paper the case of measurement data consisting in average values, and an additional prior studied by Slater, are considered.
