Limitations on quantum information from black hole physics | | Jacob D. Bekenstein
; | | Date: |
30 Sep 2001 | | Journal: | Acta Phys.Polon. B32 (2001) 3555-3570 | | Subject: | quant-ph gr-qc hep-th | | Abstract: | After reviewing the relation of entropy to information, I derive the entropy bound as applied to bounded weakly gravitating systems, and review the bound’s applications to cosmology as well as its extensions to higher dimensions. I then discuss why black holes behave as 1-D objects when emitting entropy, which suggests that a black hole swallows information at a rate restricted by the one-channel information capacity. I discuss fundamental limitations on the information borne by signal pulses in curved spacetime, from which I verify the mentioned bound on the rate of information disposal by a black hole. | | Source: | arXiv, quant-ph/0110005 | | Services: | Forum | Review | PDF | Favorites | |
