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…
Measurements in QFT: Weakly coupled local particle detectors and entanglement harvesting
Daniel Grimmer, Bruno de S. L. Torres, Eduardo Martín-Martínez
We present a comparison of the AQFT-based Fewster-Verch framework with the Unruh-DeWitt particle detector models commonly employed in relativistic quantum information and QFT in cu…
Broken covariance of particle detector models in relativistic quantum information
Eduardo Martín-Martínez, T. Rick Perche, Bruno de S. L. Torres
We show that the predictions of spatially smeared particle detectors coupled to quantum fields are not generally covariant outside the pointlike limit. This lack of covariance mani…
