相对论性量子信息:广义相对论情景下量子信息的发展

Relativistic Quantum Information: developments in Quantum Information in general relativistic scenarios

E. Martin-Martinez

摘要:

最近,人们对理解黑洞时空中的纠缠和量子通信以及使用量子信息技术来解决引力问题的兴趣越来越大。相对论纠缠的研究表明,出现了概念上重要的质的差异,以非相对论的治疗。例如,纠缠被发现是一种依赖于时间的性质,从加速观察者在平坦时空中移动的角度来看,它会发生变化。相对论量子信息理论使用来自量子信息和量子光学的众所周知的工具来研究引力引起的量子效应以了解关于时空的信息。我们可以利用我们对量子关联和引力相互作用产生的效应的了解,为最终旨在找到由于量子引力效应而引起的修正的实验方案奠定基础,这种效应太温和而无法直接观察到。这篇博士论文总结了我在博士学位期间对这个主题进行的大部分研究。

英文摘要:

Recently, there has been increased interest in understanding entanglement and quantum communication in black hole spacetimes and in using quantum information techniques to address questions in gravity. Studies on relativistic entanglement show the emergence of conceptually important qualitative differences to a non-relativistic treatment. For instance, entanglement was found to be an observer-dependent property that changes from the perspective of accelerated observers moving in flat spacetime. Relativisitic quantum information theory uses well-known tools coming from quantum information and quantum optics to study quantum effects provoked by gravity to learn information about the spacetime. We can take advantage of our knowledge about quantum correlations and effects produced by the gravitational interaction to set the basis for experimental proposals ultimately aiming at finding corrections due to quantum gravity effects, too mild to be directly observed. This doctoral thesis dissertation summarises most of the research carried out during my PhD on this topic.
