General Relativistic Quantum Physics:

Quantum theory and general relativity are famously at loggerheads. Their mathematical languages are different and conceptual bases are discordant, if not outright conflicting. For more than sixty years this conceptual gap and scant experimental evidence has been preventing unification of the two theories.

In the absence of a full quantum theory for gravity, quantum field theory in curved spacetime  is the most complete theory so far. The gravitational curvature of spacetime has nontrivial effects on quantum fields living on the spacetime when compared with their flat-spacetime counterparts. This is especially interesting in the case of dynamical spacetime backgrounds and/or when the spacetime includes horizons preventing an observer from having experimental access to the full quantum state of a field. It is known that the gravitational interaction may induce or reveal inaccessible quantum correlations in the field state in scenarios such as expanding universes or stellar collapse, and that particle detectors interacting with a quantum field can become entangled  in a way that is sensitive to the structure of the spacetime that those fields inhabit.

Relativistic Quantum Information:

How do relativistic effects influence quantum information processing? This fundamental question has developed over the past decade into the new active field of Relativistic Quantum Information. It brings together concepts and ideas from special relativity, quantum optics, general relativity, quantum communication, and quantum computation. Its aims are 1) to understand the relationship between relativistic physics and quantum information and to harness them for new techniques in quantum information processing and 2) to better comprehend the interaction of gravity and matter.
