非定域性与信息流：Deutsch和Hayden的方法
Nonlocality and information flow: The approach of Deutsch and Hayden
摘要：
Deutsch和Hayden声称已经提供了一个量子力学的解释，这个解释是特别局部的，并且澄清了纠缠量子系统中信息传输的性质。在本文中，他们的形式主义提供了一个清晰的描述和他们的要求进行评估。事实证明，有必要区分两种解释形式主义的方法，而多伊奇和海登却没有区分。第一，保守的，解释，没有利益方面的地方积累，没有已经提供的埃弗雷特或统计解释;和有关信息流的结论是模棱两可的。第二，本体论，解释，提供了一个框架的新功能，量子系统的全球性质减少到本地的，但没有结论遵循更标准的量子力学的信息流。
英文摘要：
Deutsch and Hayden claim to have provided an account of quantum mechanics which is particularly local, and which clarifies the nature of information transmission in entangled quantum systems. In this paper, a perspicuous description of their formalism is offered and their claim assessed. It proves essential to distinguish, as Deutsch and Hayden do not, between two ways of interpreting the formalism. On the first, conservative, interpretation, no benefits with respect to locality accrue that are not already available on either an Everettian or a statistical interpretation; and the conclusions regarding information flow are equivocal. The second, ontological, interpretation, offers a framework with the novel feature that global properties of quantum systems are reduced to local ones; but no conclusions follow concerning information flow in more standard quantum mechanics.
