把一个量子比特传送到埃弗雷特
Teleporting a qubit a la Everett
摘要：
如果爱丽丝和鲍勃都可以访问两个量子比特的“背景状态”，那么通过模拟埃弗雷特对测量的多世界解释，爱丽丝可以将一个量子比特传送给鲍勃，每个量子比特都使用固定的幺正。埃弗雷特图将酉、测量和经典通信统一为酉，前提是所有各方都有共享的背景状态。我们回顾了一些关于这个主题的文献，并指出一个额外的事实：如果鲍勃只能访问一个背景量子位，通过爱丽丝向鲍勃发送一个从另一个量子位的测量中获得的经典信息位，隐形传态仍然是可能的。
英文摘要：
If both Alice and Bob have access to a two-qubit "background state" then, by simulating Everett's many worlds interpretation of measurement, Alice can teleport a qubit to Bob, each using fixed unitaries. The Everett picture unifies unitaries, measurements, and classical communication into just unitaries, provided there are background states shared by all parties. We review some of the literature on this theme and point out an additional fact: If Bob has access to only one of the background qubits, teleportation is still possible by Alice sending Bob one classical bit of information gained from a measurement of the other qubit.
