Prospects in relativistic quantum information - Achim Kempf

Quantum information theoretic tools can be used to study basic physical phenomena. For example, the study of the quantum channel of communicating Unruh deWitt detectors resolves an old Fermi problem. Quantum entanglement can even be used, in principle, and possibly also experimentally, to detect curvature. This in turn could allow one to understand spatial curvature in new and purely quantum information theoretic terms, namely as a modulation of the local information carrying capacity of space. The underlying mathematics also yields new results on Kac's question 'Can one hear the shape of a drum?'.
