We address the validity of the single-mode approximation that is commonly invoked in the
analysis of entanglement in noninertial frames and in other relativistic quantum-information …

We analyze the entanglement degradation provoked by the Hawking effect in a bipartite
system Alice-Rob when Rob is in the proximities of a Schwarzschild black hole while Alice is …

Understanding the observer-dependent nature of quantum entanglement has been a central
question in relativistic quantum information. In this paper, we will review key results on …

We review recent literature on the connection between quantum entanglement and
cosmology, with an emphasis on the context of expanding universes. We discuss recent …

The bipartite and tripartite entanglement of a 3-qubit fermionic system when one or two
subsystems accelerate are investigated. It is shown that all the one-tangles decrease as the …

We analyze the entanglement tradeoff between particle and antiparticle modes of a Dirac
field from the perspective of inertial and uniformly accelerated observers. Our results show …

We analyze the entanglement tradeoff between particle and antiparticle modes of a charged
bosonic field between inertial and uniformly accelerated observers. In contrast with previous …

We analyze families of particle detector models that linearly couple to different kinds of
fermionic and bosonic fields. We also study the response of these detectors to particle and …

We analyze correlations between pairs of particle detectors quadratically coupled to a real
scalar field. We find that, while a single quadratically coupled detector presents no …

We study the entanglement of families of Unruh modes in the Bell states| Φ±〉= 1/2 (| 00〉±|
11〉) and| Ψ±〉= 1/2 (| 01〉±| 10〉) shared by two accelerated observers and find …
