Relativistic Quantum Information and Technologies

在过去的十年里，出现了一个高研究强度的新领域--相对论量子信息(RQI)领域。RQI将信息论与现代物理学的两大支柱--广义相对论和量子理论结合在一起。RQI领域的成果从对自然规律的新见解(例如黑洞物理和宇宙学)一直到量子计算和量子安全通信的具体应用。特别是，由于理论和技术的进步，量子信息处理中的相对论效应的研究最近变得更加重要：量子光学、超导电路和玻色-爱因斯坦凝聚体的实验现在可以探索相对论对量子信息的影响。将纠缠分布在数百公里范围内的协议现在正在达到相对论效应变得重要的状态，卫星实验正在开发中，这些实验将测量引力对量子纠缠的影响。

Over the past decade, a new field of high research intensity has emerged, the field of Relativistic Quantum Information (RQI). RQI brings together information theory with the two pillars of modern physics: General relativity and quantum theory. The results in the field of RQI range from new insights into the laws of Nature (e.g. black hole physics and cosmology) all the way to concrete applications in quantum computing and quantum-secured communication. In particular, the study of relativistic effects in quantum information processing has recently become more important due to improvements both in theory and in technology: Experiments in quantum optics, superconducting circuits and Bose-Einstein condensates can now probe relativistic influences on quantum information. Protocols that distribute entanglement over hundreds of kilometers are now reaching regimes where relativistic effects are becoming important, and satellite experiments are being developed that will measure gravitational effects on quantum entanglement.
