Recent progress in deriving the Page curve for unitary black hole evaporation is a significant step towards finding both a resolution to the information paradox and a more general understanding of unitarity in quantum gravity. [21] Many researchers consider deriving the Page curve as synonymous with solving the black hole information paradox.
The thought experiment concerning Alice and Bob is as follows: Alice throws a k qubit quantum state into a black hole that is entangled with Bob's quantum computer. Bob collects the Hawking radiation emitted by the black hole and feeds it into his quantum computer where he applies the appropriate quantum gates that will decode Alice's state.
The simplest models of black hole evaporation lead to the black hole information paradox. The information content of a black hole appears to be lost when it dissipates, as under these models the Hawking radiation is random (it has no relation to the original information).
Stephen Hawking’s suggestion that black holes “leak” radiation left physicists with a problem they have been attempting to solve for 51 years.
In 1974, Hawking predicted that black holes might not be the bottomless pits we imagine them to be -- and now, there may be evidence to support that theory.
The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell.
The holographic principle as used in a resolution of this paradox implies that the information is encoded at the event horizon of a black hole, and is released as part of the Hawking radiation. Therefore it's part of the approach given, Information gradually leaks out during the black-hole evaporation. However, it might be worth expanding on ...
Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics is a 2008 popular science book by American theoretical physicist Leonard Susskind. The book covers the black hole information paradox , and the related scientific dispute between Stephen Hawking and Susskind. [ 1 ]
