The decade of the 2000s has seen the birth of the fast-growing field of Relativistic Quantum Information (RQI). RQI brings together the two pillars of modern physics, general relativity and quantum theory, with information theory. 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 developments both in theory and in technology. Experiments in quantum optics, superconducting circuits and Bose-Einstein condensates can now probe relativistic influences on quantum information technologies. Protocols that distribute entanglement over hundreds of kilometres are now reaching regimes where relativistic effects are important, and satellite experiments are being developed that will measure gravitational effects on quantum entanglement. On the fundamental side, RQI addresses, for instance, how curvature and quantum theory impact the flow and the processing of information. For example, RQI is concerned with the role of relativistic quantum entanglement in black hole physics and in cosmology, and with the developing of new mathematical methods for the quantization of gravity.

On June 21, Relativistic Quantum Information North - 2016 is going to be held at the Institute for Quantum Computing at the University of Waterloo, with the additional support of the Perimeter Institute for Theoretical Physics, the Fields Institute and the Institute for Quantum Science and Technology. This conference will gather some of the most prominent researchers in RQI (as well as some of their best postdoctoral fellows and brilliant graduate students) to discuss deep questions concerning the relationship between information processing and the structure of spacetime.

RQI-N 2016 is the seventh RQI-N international conference since the beginning of the series in 2010, and in 2016 it could not be more timely. This event is happening in the middle of a plethora of newly emerging prospects for experimental tests of phenomena of Relativistic Quantum Information. It just takes a glance at the schedule to see that we are bringing together a group of the most prominent world-class theoretical physicists working on Information Theory, Quantum Theory and Gravity, with experimenters capable of reproducing the physics of a black hole in a table top-experiment or generating entangled light out of fluctuations of the quantum vacuum.

In this forum we will share our research and aim to answer some of the most important questions in Relativistic Quantum Information, for example: What relativistic settings have an advantage over non-relativistic ones in quantum information technologies such as quantum cryptography or computing? Can the fluctuations of a quantum field provide a renewable source of quantum entanglement? Can we teleport energy by sending just information? Can we use quantum simulators in superconducting circuits or quantum optical settings to study early universe physics? What remains after a black hole evaporates? Can information theory help us find a theory of quantum gravity? How much information has been transmitted from the early universe to today? How much of it is readable?

The conference's research agenda has the unique feature of combining fundamental physics (relativistic approaches to quantum theory) with “real-world” experimental and technological applications. From the use of relativity to enhance quantum technologies to the simulation of cosmology in superconducting circuits and optical cavities, RQI-N is a forum for revolutionary ideas with the potential to impact numerous disciplines in fundamental physics, applied science and technology. Myself and the other organizers are looking forward to the conference and we hope that you can join us this year in this event.
