论文摘要
在量子达尔文主义中，可观察到的系统的指针在破裂后在其环境中留下了冗余的烙印。每个烙印都记录在环境的一部分中，该环境标识了环境的特定分区。当另一个可观察到的指针可观察到的可观察到的不合理的情况下，还会出现有关环境另一个分区的冗余烙印时，可能会发生歧义情况。我们根据我们证明的唯一性定理研究了这个问题。我们发现，在环境的所有可能分区的特定子集中，可观察到的系统在环境中留下冗余和非平衡记录的烙印是独一无二的。而且，在典型的情况下，该特定子集之外的分区没有物理意义。
In quantum Darwinism, the pointer observable of a system leaves redundant imprints in its environment after decoherence. Each imprint is recorded in a fraction of the environment, which identifies a particular partition of the environment. An ambiguity situation may occur when another observable noncommuting to the pointer observable also leaves redundant imprints with respect to another partition of the environment. We study this problem based on a uniqueness theorem we proved. We find that within a particular subset of all possible partitions of the environment, the observable of the system leaving redundant and nondegenerately recorded imprints in the environment is unique. And, in a typical situation, the partitions outside this particular subset have no physical significance.
