Relativistic Quantum Information and Technologies

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.
