退相干、反选择和势解释(粗略指南)
Decoherence, Einselection, and the Existential Interpretation (the Rough Guide)
摘要:
描述了退相干和环境诱导的超选择在从量子衬底中产生经典中的作用。非选定量子指针态与环境之间的关联稳定性使得它们几乎像经典态曾经被认为存在的那样客观地存在:有一些方法可以找到系统的指针态,这些方法利用它们与环境的关联冗余,并且使非选定态基本上不受扰动。某些量子态的这种相对客观的存在有利于量子环境中概率的操作定义。此外,一旦有状态“存在”并且可以“发现”,传统意义上的“崩溃”就不再必要了--实际上,它已经发生了。观察者的记录将包含有效崩溃的证据。的作用,在处理和存储的信息的首选状态被强调。存在性解释的基础上的相对客观存在的稳定的相关性之间的einselected状态的观察者记忆和外部宇宙的制定和讨论。
英文摘要:
The roles of decoherence and environment-induced superselection in the emergence of the classical from the quantum substrate are described. The stability of correlations between the einselected quantum pointer states and the environment allows them to exist almost as objectively as classical states were once thought to exist: There are ways of finding out what is the pointer state of the system which utilize redundancy of their correlations with the environment, and which leave einselected states essentially unperturbed. This relatively objective existence of certain quantum states facilitates operational definition of probabilities in the quantum setting. Moreover, once there are states that `exist' and can be `found out', a `collapse' in the traditional sense is no longer necessary --- in effect, it has already happened. The records of the observer will contain evidence of an effective collapse. The role of the preferred states in the processing and storage of information is emphasized. The existential interpretation based on the relatively objective existence of stable correlations between the einselected states of observers memory and in the outside Universe is formulated and discussed.
