How cosmological expansion affects communication between distant quantum systems
Alessio Lapponi, Orlando Luongo, Stefano Mancini
A quantum communication protocol between harmonic oscillator detectors, interacting with a quantum field, is developed in a cosmological expanding background. The aim is to see if…
Horizon entanglement area law from regular black hole thermodynamics
Alessio Belfiglio, S. Mahesh Chandran, Orlando Luongo +1
We investigate the thermodynamics of regular black hole configurations via quantum analogs of entropy and energy -- namely, the entanglement entropy and entanglement energy -- near…
Preserving quantum information in cosmology
Salvatore Capozziello, Alessio Lapponi, Orlando Luongo +1
The effects of cosmological expansion on quantum bosonic states are investigated, using quantum information theory. In particular, a generic Bogoliubov transformation of bosonic fi…
Making two particle detectors in flat spacetime communicate quantumly
Alessio Lapponi, Jorma Louko, Stefano Mancini
A communication protocol with non-zero quantum capacity is found when the two communicating parts are particle detector models in (3+1)-dimensional spacetime. In particular, as det…
Entanglement entropy in quantum black holes
Alessio Belfiglio, Orlando Luongo, Stefano Mancini +1
We discuss the entanglement entropy for a massive Klein-Gordon field in two Schwarzschild-like quantum black hole spacetimes, also including a nonminimal coupling term with the bac…
Geometric and topological corrections to Schwarzschild black hole
Rocco D'Agostino, Orlando Luongo, Stefano Mancini
In this paper, we compute departures in the black hole thermodynamics induced by either geometric or topological corrections to general relativity. Specifically, we analyze the sph…
