Not One Bit of de Sitter Information | | Maulik K. Parikh
; Jan Pieter van der Schaar

2 Apr 2008 | | Abstract: | We formulate the information paradox in de Sitter space in terms of the
no-cloning principle of quantum mechanics. We show that energy conservation
puts an upper bound on the maximum entropy available to any de Sitter observer.
Combined with a general result on the average information in a quantum
subsystem, this guarantees that an observer in de Sitter space cannot obtain
even a single bit of information from the de Sitter horizon, thereby preventing
any observable violations of the quantum no-cloning principle, in support of
observer complementarity. | | Source: | arXiv, 0804.0231 | | Services: | Forum | Review | PDF | Favorites | |
