论文摘要
量子达尔文主义通过与环境的相关性来描述量子系统的客观性 - 假设观察者可以通过测量环境恢复的信息。但是，观察是关于参考框架的。在这里，我们采用[Giacomini，Castro-Ruiz和Brukner的形式主义。 Nat Commun 10，494（2019）]，并考虑更改量子参考帧时对客观性的影响。我们发现客观性取决于非分离性相对分离，条件状态定位和环境宏观分流。由于纠缠与连贯性的互换性以及统计混合和经典相关性，不同参考框架中有不同的客观信息。因此，客观性在量子参考框架上是主观的。
Quantum Darwinism describes objectivity of quantum systems via their correlations with their environment--information that hypothetical observers can recover by measuring the environments. However, observations are done with respect to a frame of reference. Here, we take the formalism of [Giacomini, Castro-Ruiz, & Brukner. Nat Commun 10, 494 (2019)], and consider the repercussions on objectivity when changing quantum reference frames. We find that objectivity depends on non-degenerative relative separations, conditional state localisation, and environment macro-fractions. There is different objective information in different reference frames due to the interchangeability of entanglement and coherence, and of statistical mixing and classical correlations. As such, objectivity is subjective across quantum reference frames.
