论文摘要
埃弗里特（Everett）在量子理论中的相对状态结构从未在海森伯格（Heisenberg）图片中令人满意地表达。我们在这里解决的概念和技术问题阻碍了人们可能期望的直接过程。结果是一种结构，与埃弗里特（Everett）在schrödinger图片中的结构不同，它使埃弗里特（Everettian）多样性及其固有的近似性质及其起源在某些类型的纠缠和本地无法访问的信息中显现出来。我们的构造还使我们可以对Everett“宇宙”提供更精确的定义，在该定义下，它是完全量子的，而不是准经典的，我们将量子状态的Everettian分解与时空的叶子进行了比较。
Everett's relative-state construction in quantum theory has never been satisfactorily expressed in the Heisenberg picture. What one might have expected to be a straightforward process was impeded by conceptual and technical problems that we solve here. The result is a construction which, unlike Everett's one in the Schrödinger picture, makes manifest the locality of Everettian multiplicity, and its inherently approximative nature, and its origin in certain kinds of entanglement and locally inaccessible information. Our construction also allows us to give a more precise definition of an Everett 'universe', under which it is fully quantum, not quasi-classical, and we compare the Everettian decomposition of a quantum state with the foliation of a spacetime.
