Harvesting entanglement with detectors freely falling into a black hole
We carry out the first investigation of the entanglement and mutual information harvesting
protocols for detectors freely falling into a black hole. Working in (1+ 1)-dimensional …

Geometry of spacetime from quantum measurements
TR Perche, E Martín-Martínez - Physical Review D, 2022 - APS
We provide a setup by which one can recover the geometry of spacetime from local
measurements of quantum particle detectors coupled to a quantum field. Concretely, we …

Harvesting correlations from thermal and squeezed coherent states
P Simidzija, E Martin-Martinez - Physical Review D, 2018 - APS
We study the harvesting of entanglement and mutual information by Unruh-DeWitt particle
detectors from thermal and squeezed coherent field states. We prove (for arbitrary spatial …

Quantum temporal superposition: the case of quantum field theory
Quantum field theory is completely characterized by the field correlations between
spacetime points. In turn, some of these can be accessed by locally coupling to the field …

Effective master equations for two accelerated qubits
G Kaplanek, E Tjoa - Physical Review A, 2023 - APS
We revisit the problem involving two constantly accelerating Unruh-DeWitt detectors using
open effective field theory methods. We study the time evolution of the joint detector state …

Bandlimited entanglement harvesting
LJ Henderson, NC Menicucci - Physical Review D, 2020 - APS
There are many reasons to believe that there is a fundamental minimum length scale below
which distances cannot be reliably resolved. One method of constructing a quantum field …

Transmission of quantum information through quantum fields
We investigate the quantum channel consisting of two localized quantum systems that
communicate through a scalar quantum field. We choose a scalar field rather than a tensor …

Role of quantum degrees of freedom of relativistic fields in quantum information protocols
TR Perche, E Martín-Martínez - Physical Review A, 2023 - APS
We analyze the differences between relativistic fields with or without quantum degrees of
freedom in relativistic quantum information protocols. We classify the regimes where the …
