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.

在过去的十年中，出现了一个高研究强度的新领域，即相对论量子信息（RQI）领域。RQI将信息理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（例如黑洞物理学和宇宙学）的新见解一直到量子计算和量子安全通信的具体应用。特别是量子信息处理中的相对论效应的研究最近由于理论和技术的改进而变得更加重要：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测相对论对量子信息的影响。在数百公里范围内传播纠缠的协议现在已经达到了相对论效应变得重要的程度，正在开发的卫星实验将测量引力对量子纠缠的影响。
