Abstract

Black holes, fundamental destruction of information and conservation laws

Theories which have fundamental information destruction or decoherence are motivated by the black hole information paradox where one appears to have pure states evolving into mixed states. However such theories have generally been disregarded because they either violate conservation laws, or are highly non-local. Here, we show that the tension between conservation laws and locality can be circumvented by constructing a relational theory in which pure states evolve to mixed states. This allows for the possibility of a less radical solution to the black hole information puzzle. http://arxiv.org/abs/0902.2361
