Abstract

This is a synopsis of our recent work [1] on quantum entanglement, quantum coherence and information flow between a uniformly accelerated detector and a massless quantum scalar field. The availability of exact solutions to this model enables us to explore some important aspects of the black hole information issue with some quantifiable results and new insights. To the extent this model can capture the essence of quantum coherence, entanglement and information flow between a black hole and its Hawking radiation, our result seems to suggest that in the prevalent non-Markovian regime, assuming unitarity holds for the combined system which is a dictum of physical laws, that black hole information is not lost or stored in the correlations between the black hole and the quantum field but totally transferred to the quantum field degrees of freedom. This combined system would evolve into a highly entangled state between a remnant of large area (in Bekenstein's black hole atom analog) losing all information of its initial state, while the quantum field is imbued with complex information content not-so-easily retrievable by a local observer.
