Quantum coherence and quantum correlations are of fundamental and practical significance
for the development of quantum mechanics. They are also cornerstones of quantum …

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 study the entanglement generated between Dirac modes in a 2-dimensional conformally
flat Robertson-Walker universe. We find radical qualitative differences between the bosonic …

We apply genuine multipartite entanglement concurrence to investigate entanglement
properties of Dirac fields in noninertial frames. We present analytical concurrences for …

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 …

The classical and quantum correlation sharing between modes of Dirac fields in the
noninertial frame are investigated. It is shown that (i) the classical correlation for the Dirac …

We review recent results regarding entanglement in quantum fields in cosmological
spacetimes and related phenomena in flat spacetime such as the Unruh effect. We begin …

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 …
