Zero mode, Zero influence: Spatial-derivative coupling in particle detectors
Eduardo Martín-Martínez, Ireneo James Membrere, Adam Teixidó-Bonfill
It is common in particle detector models in cavity QED to often omit zero modes or assume their state, compromising causality or introducing ambiguity in their predictions. We show…
Nonlinear particle detectors across the Rindler firewall
Matheus H. Zambianco, Eduardo Martín-Martínez
We investigate Unruh-DeWitt detectors coupled to composite observables of a quantum scalar field, including quadratic coupling to the field momentum and coupling to the local energ…
Ultraviolet structure of entanglement harvesting from energy density and other quadratic couplings
Matheus H. Zambianco, Boris Ragula, Eduardo Martín-Martínez
We study entanglement harvesting with particle detectors coupled to the renormalized energy density of a massless scalar field. Our analysis identifies the distributional mechanism…
Cosmological Expansion Induces Interference Between Communication and Entanglement Harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo Martín-Martínez
We investigate the interplay between genuine entanglement harvesting and communication mediated correlations for local particle detectors in expanding cosmological spacetimes. Focu…
Entanglement harvesting in conformal field theory
Kelly Wurtz, Caroline Lima, Robert C. Myers +1
We study entanglement harvesting in general -dimensional conformal field theories using pointlike Unruh-DeWitt detectors coupled to scalar primary operators. This extends standa…
State updates and useful qubits in relativistic quantum information
José Polo-Gómez, T. Rick Perche, Eduardo Martín-Martínez
We address the longstanding challenge of consistently updating quantum states after selective measurements in a relativistic spacetime. Standard updates along the future lightcones…
Towards an experimental implementation of entanglement harvesting in superconducting circuits: effect of detector gap variation on entanglement harvesting
Adam Teixidó-Bonfill, Xi Dai, Adrian Lupascu +1
Motivated by the prospect of experimental implementations of entanglement harvesting in superconducting circuits, we propose a model of variable-gap particle detector that aims to…
A review of applications of Quantum Energy Teleportation: from experimental tests to thermodynamics and spacetime engineering
Boris Ragula, Eduardo Martín-Martínez
Quantum energy teleportation (QET) exploits the existence of correlations to enable remote energy transfer without the need for physical energy carriers between emitter and receive…
