AI 中文摘要
有时人们会说，偏爱埃弗雷特量子力学（EQM）的一个理由是，它能让人们避免其他量子力学诠释中因量子纠缠产生的那种幽灵般的超距作用。有一个简单的论证可表明EQM具备这一优点，不过一些支持者认为，这要求我们将分支视为一种局域因果过程。我解释了这一推理，随后证明，鉴于埃弗雷特主义者将世界和分支标准地构想为涌现现象的方式，对于EQM而言，分支无需被视为因果过程也能满足相对论局域性。该成果即将发表于《局域量子力学》（牛津大学出版社，2026年）。
英文摘要
It is sometimes said that a reason to prefer Everettian quantum mechanics is that it allows one to avoid the kind of spooky action at a distance that is a consequence of quantum entanglement according to other approaches. There is a straightforward argument to show EQM has this virtue, however some advocates argue that this requires we see branching as a local causal process. I explain this reasoning and then show why, given the way Everettians standardly conceive of worlds and branching as emergent phenomena, branching need not be viewed as a causal process for EQM to be relativistically local.
