A noisy quantum channel model for the cosmological horizon in de Sitter spacetime

10 Oct 2019 Bak Sang-Eon Alsing Paul M. Miller Warner A. Ahn Doyeol

Quantum correlation between two observers across the cosmological horizon and retrieval of the information behind the cosmological horizon are investigated in the frame of de Sitter spacetime. It is also shown that the effect of the Universe expansion can be described by a noisy quantum channel model having a complete positive map with an operator sum representation... (read more)
