Ultraviolet structure of entanglement harvesting from energy density and other quadratic couplings
Matheus H. Zambianco, Boris Ragula, Eduardo MartÃn-MartÃnez
The paper analyzes how particle detectors coupled to the renormalized energy density of a massless scalar field can harvest entanglement, identifying the ultraviolet divergences as…
Nonlinear particle detectors across the Rindler firewall
Matheus H. Zambianco, Eduardo MartÃn-MartÃnez
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…
Cosmological Expansion Induces Interference Between Communication and Entanglement Harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo MartÃn-MartÃnez
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 MartÃn-MartÃnez
We address the longstanding challenge of consistently updating quantum states after selective measurements in a relativistic spacetime. Standard updates along the future lightcones…
A review of applications of Quantum Energy Teleportation: from experimental tests to thermodynamics and spacetime engineering
Boris Ragula, Eduardo MartÃn-MartÃnez
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…
