Unitary (semi)causal quantum-circuit representation of black hole evaporation
Bogusław Broda
A general structure of unitary evolution (evaporation) of the black hole, respecting causality imposed by the event horizon (semicausality), has been derived and presented in the l…
Causal unitary qubit model of black hole evaporation
Bogusław Broda
A new simple qubit model of black hole evaporation is proposed. The model operates on four qubits and is defined in terms of quantum gates and a quantum circuit. The chief features…
Fermionic model of unitary transport of qubits from a black hole
Bogusław Broda
Inspired by a recent model of Osuga and Page, we propose an explicitly unitary fermionic toy model for transferring information from a black hole to the outgoing radiation. The mod…
Unitary toy qubit transport model for black hole evaporation
Bogusław Broda
In a recent paper Osuga and Page have presented an explicitly unitary toy qubit transport model for transferring information from a black hole to the outgoing radiation. Following…
Unitary evolution to a state with a fixed mean number of particles
Bogusław Broda
In the framework of finite-dimensional Fock space models, for a predefined fixed mean number of particles , it is shown that there is a ``large'' multi-dimensional sub…
Total spectral distributions from Hawking radiation
Bogusław Broda
Taking into account time-dependence of the Hawking temperature and finite evaporation time of the black hole, total spectral distributions of the radiant energy and of the number o…
