Can Hawking effect of multipartite state protect quantum resources in Schwarzschild black hole?
Shu-Min Wu, Xiao-Wei Teng, Hui-Chen Yang +3
Most previous studies on relativistic quantum information have primarily focused on the vacuum state and the first excited state in two-mode entangled syste…
Velocity effects slightly mitigating the quantumness degradation of an Unruh-DeWitt detector
P. H. M. Barros, Shu-Min Wu, C. A. S. Almeida +1
In this work, we investigate the velocity effects on information degradation due to the Unruh effect in accelerated quantum systems (with finite interaction time). We consider a de…
Transition rates and their applications in accelerated single-qubit for fermionic spinor field coupling
Arnab Mukherjee, Sunandan Gangopadhyay, P. H. M. Barros +1
In this work, we investigate the interaction between a uniformly accelerated single qubit and a fermionic spinor field. Here we consider both the massless and the massive fermionic…
On the information behavior from quadratically coupled accelerated detectors
P. H. M. Barros, P. R. S. Carvalho, H. A. S. Costa
In this work, we propose to investigate the information behavior of quantum systems through accelerated detectors quadratically coupled with a massless scalar field. In addition, w…
Mitigating the information degradation in a massive Unruh-DeWitt theory
P. H. M. Barros, F. C. E. Lima, C. A. S. Almeida +1
We investigated the influence of the massive scalar field on the information degradation concerning the Unruh-DeWitt (UDW) detectors. In this conjecture, we adopted a system with a…
Dispersive vacuum as a decoherence amplifier of an Unruh-DeWitt detector
Pedro H. M. Barros, Helder A. S. Costa
Recently, interest has been growing in studies on discrete or "pixelated" space-time that, through modifications in the dispersion relation, can treat the vacuum as a dispersive me…
