Quantum technologies in relativistic regimes.
We are living in the Quantum Era. Quantum features, such as entanglement, have enabled the discovery of many exciting phenomena, and are now being exploited in the development of futuristic technologies. Quantum computing and quantum communications are only two of the foreseen applications. Furthermore, cutting-edge experiments are being proposed to operate in regimes where relativity plays a role. In such situations, relativity is included as an ad-hoc modification of the standard Schrödinger equation. Regardless of the advances within their respective domains, relativity and quantum mechanics are fundamentally incompatible. It is an open question how to properly describe and characterise quantum technologies in regimes where relativity is important.
In this work we give an overview of the recent progress in the field of relativistic quantum information, focusing on the role of quantum correlations in relativistic and quantum science. We focus on the role correlations play in small, localised quantum system and discuss how they can be exploited to extract information about relativistic properties of such systems. This allows us to uniquely identify relativistic contributions to a plethora of measurements, which can lead high-precision measurements of relativistic parameters. We conclude with a discussion on potential implementations in Bose-Einstein Condensates and optomechanical systems.
