The present paper is both a review on the Feynman problem, and an original research
presentation on the relations between Fermionic theories and qubits theories, both regarded …

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 investigate the performance of quantum Fisher information (QFI) under the Unruh-
Hawking effect, where one of the observers (eg, Rob) is uniformly accelerated with respect …

We analyze fermionic modes as fundamental entities for quantum information processing.
To this end we construct a density operator formalism on the underlying Fock space and …

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

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 …

Since quantum field theories do not possess proper position observables, Unruh-DeWitt
detector models serve as a key theoretical tool for extracting localized spatiotemporal …

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 …

We show that the computational model based on local fermionic modes in place of qubits
does not satisfy local tomography and monogamy of entanglement, and has mixed states …
