Entanglement in anisotropic expanding spacetime
Roberto Pierini, Shahpoor Moradi, Stefano Mancini
We study the effect of space anisotropy in the entanglement generated by expanding universe on spin 0 and 1/2 fields. For massive scalar field we find revivals of entanglement entr…
Effects of gravity on quantum key distribution
Roberto Pierini
The domain of quantum technologies has been recently broaden to satellites orbiting the earth. Long distances communication protocols cannot ignore the presence of the gravitationa…
Can a charged decaying particle serve as an ideal clock in the presence of the magnetic field?
Roberto Pierini, Krzysztof Turzynski, Andrzej Dragan
We investigate a model of a supposedly ideal clock based on the decay rate of a charged particle in circular motion in a constant magnetic field. We show that the time measured by…
Spacetime anisotropy affects cosmological entanglement
Roberto Pierini, Shahpoor Moradi, Stefano Mancini
Most existing cosmological entanglement studies are focused on the isotropic Robertson-Walker (RW) spacetime. Here we go beyond this limitation and study the influence of anisotrop…
The role of spin in entanglement generated by expanding spacetime
Roberto Pierini, Shahpoor Moradi, Stefano Mancini
We investigate the effects of spin on entanglement arising in Dirac field in an expanding spacetime characterized by the Robertson-Walker metric. We present a general approach that…
