چکیده
A new simple qubit model of black hole evaporation is proposed. The operates on four qubits and defined in terms quantum gates a circuit. chief features the include explicit unitarity (most notably) causality which understood as impossibility transfer information from interior through its horizon. corresponding von Neumann entanglement entropy yields crude (four-qubit) approximation Page curve.

Unitary Rules for Black Hole Evaporation
Hawking has proposed non-unitary rules for computing the probabilistic outcome of black hole formation. It is shown that the usual interpretation of these rules violates the superposition principle and energy conservation. Refinements of Hawking’s rules are found which restore both the superposition principle and energy conservation, but leave completely unaltered Hawking’s prediction of a ther...
متن کاملQuantum black hole evaporation.
We investigate a recently proposed model for a full quantum description of two-dimensional black hole evaporation, in which a reflecting boundary condition is imposed in the strong coupling region. It is shown that in this model each initial state is mapped to a well-defined asymptotic out-state, provided one performs a certain projection in the gravitational zero mode sector. We find that for ...
متن کاملControl of black hole evaporation?
Contradiction between Hawking’s semi-classical arguments and string theory on the evaporation of black hole has been one of the most intriguing problems. Previously, a final-state boundary condition inside the black hole was proposed by Horowitz and Maldacena to resolve this contradiction. We point out that original Hawking effect can be regarded as a separate boundary condition at the event ho...
متن کاملBlack Hole Evaporation. A Survey
This thesis is a review of black hole evaporation with emphasis on recent results obtained for two dimensional black holes. First, the geometry of the most general stationary black hole in four dimensions is described and some classical quantities are defined. Then, a derivation of the spectrum of the radiation emitted during the evaporation is presented. In section four, a two dimensional mode...
متن کاملBlack Hole Evaporation and Complementarity ∗
About twenty years ago Hawking made the remarkable suggestion that the black hole evaporation process will inevitably lead to a fundamental loss of quantum coherence [1]. The mechanism by which the quantum radiation is emitted appears to be insensitive to the detailed history of the black hole, and thus it seems that most of the initial information is lost for an outside observer. However, dire...
