论文摘要
客观性问题，即如何从量子基础上解释宏观世界的客观特征，是著名的量子到古典过渡的方面之一。该问题由W. H. Zurek和合作者发起，最近通过开发了几种方法引起了一些关注。这项工作的目的是比较其中的三个：量子达尔文主义，频谱广播结构和强大的量子达尔文主义。本文集中在基础上，提供了三种方法如何实现客观性及其彼此相关的综合分析。作为该分析的副产品，提出了广义频谱广播结构定理的证明。还简要讨论了最近的量子达尔文主义实验。
The problem of objectivity, i.e. how to explain on quantum grounds the objective character of the macroscopic world, is one of the aspects of the celebrated quantum-to-classical transition. Initiated by W. H. Zurek and collaborators, this problem gained some attention recently with several approaches being developed. The aim of this work is to compare three of them: quantum Darwinism, Spectrum Broadcast Structures, and strong quantum Darwinism. The paper is concentrated on foundations, providing a synthetic analysis of how the three approaches realize the idea of objectivity and how they are related to each other. As a byproduct of this analysis, a proof of a generalized Spectrum Broadcast Structure theorem is presented. Recent quantum Darwinism experiments are also briefly discussed.
