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…
The multimode nature of spacetime entanglement in QFT
Ivan Agullo, Béatrice Bonga, Eduardo Martín-Martínez +5
We demonstrate the presence of multimode entanglement in the vacuum state of a free, massless scalar quantum field in four-dimensional flat spacetime between two sets of field mode…
Non-perturbative method for particle detectors with continuous interactions
José Polo-Gómez, Eduardo Martín-Martínez
We show that detector switching profiles consisting of trains of delta couplings are a useful computational tool to efficiently approximate results involving continuous switching f…
Fully Relativistic Entanglement Harvesting
T. Rick Perche, José Polo-Gómez, Bruno de S. L. Torres +1
We study the protocol of entanglement harvesting when the particle detectors that harvest entanglement from the field are replaced by fully relativistic quantum field theories. We…
Particle Detectors from Localized Quantum Field Theories
T. Rick Perche, José Polo-Gómez, Bruno de S. L. Torres +1
We present a fully relativistic model for localized probes in quantum field theory. Furthermore, we show that it is possible to obtain particle detector models from localized quant…
How measuring a quantum field affects entanglement harvesting
Héctor Maeso-García, José Polo-Gómez, Eduardo Martín-Martínez
We analyzed how entanglement harvesting is affected by the performance of a measurement on the quantum field. The measurement on the field is modelled as the coupling of a particle…
Entanglement harvesting: state dependence and covariance
Héctor Maeso-García, José Polo-Gómez, Eduardo Martín-Martínez
We analyze entanglement harvesting for arbitrary initial states of particle detectors and arbitrary quasifree states of the field. Despite the fact that spatially smeared particle…
