Limitations on quantum information from black hole physics
نویسنده
چکیده
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.

Quantum Information and Quantum Black Holes
First, the relation between black holes and limitations on information of other systems is developed. After reviewing the relation of entropy to information, we derive the entropy bound, review its applications to cosmology and its extensions to higher dimensions, and discuss why black holes behave as 1-D objects when emitting entropy. We also discuss fundamental limitations on the information ...
متن کاملQuantum Information and Gravity Cutoff in Theories with Species
We show that lowering of the gravitational cutoff relative to the Planck mass, imposed by black hole physics in theories with N species, has an independent justification from quantum information theory. First, this scale marks the limiting capacity of any information processor. Secondly, by taking into the account the limitations of the quantum information storage in any system with species, th...
متن کاملThe phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
متن کاملComplete Semiclassical Treatment of the Quantum Black Hole Problem
Two types of semiclassical calculations have been used to study quantum effects in black hole backgrounds, the WKB and the mean field approaches. In this work we systematically reconstruct the logical implications of both methods on quantum black hole physics and provide the link between these two approaches. Our conclusions completely support our previous findings based solely on the WKB metho...
متن کاملUnitarity, nonlocality, and black hole information
Hawking’s argument for black hole information loss is reassessed. A precise characterization of missing information in outgoing Hawking radiation is the entropy, computed from elements of the density matrix. The statement that these elements can be derived in a controlled semiclassical approximation is examined via a calculation of matrix elements of the stress tensor, and argued to be flawed b...
