Quantum information meets quantum gravity

黑洞和量子引力是遥远的现象，目前还无法通过实验获得，但是——在一个可能被称为物理学的不合理连通性的例子中——量子场论、凝聚态物理和量子引力现在都在使用量子信息理论的相同工具，并面临许多相同的潜在问题。这种情况导致了研究领域之间思想的高效多向流动。该项目将运用量子信息理论的思想来理解量子引力的各个方面，特别是黑洞信息问题。重点可能包括理解信息损失（基本的或有效的），并克服这种信息损失与量子场论的其他方面（如局部性和守恒定律）之间的紧张关系。

Black holes and quantum gravity are remote phenomena that cannot at present be accessed experimentally, but - in an example of what might be called the unreasonable connectivity of physics - quantum field theory, condensed-matter physics, and quantum gravity are now all using the same tools of quantum information theory, and confronting many of the same underlying problems. This circumstance has led to a highly productive multidirectional flow of ideas among research areas. This project will apply ideas from quantum information theory to understand aspects of quantum gravity, and in particular the black hole information problem. Focus is likely to include understanding information loss (fundamental or effective) and overcoming the tension between such information loss and other aspects of quantum field theory such as locality and conservation laws.
