We study how two fully featured hydrogenlike atoms harvest entanglement from the
electromagnetic field vacuum, even when the atoms are spacelike separated. We compare …

Causality is a seminal concept in science: Any research discipline, from sociology and
medicine to physics and chemistry, aims at understanding the causes that could explain the …

We analyze a quantum observer who falls geodesically toward the Cauchy horizon of a (1+
1)-dimensional eternal black hole spacetime with the global structure of the non-extremal …

Quantum theory, as counter-intuitive as a theory can get, has turned out to make predictions
of the physical world that match observations so precisely that it has been described as the …

We study how quantum randomness generation based on unbiased measurements on a
hydrogen-like atom can get compromised by the unavoidable coupling of the atom with the …

In this thesis, we study the interaction of a first-quantized atomic system with the quantum
electromagnetic field within the context of relativistic quantum information (RQI). To that end …
