Causality in relativistic quantum interactions without mediators
Eirini C. Telali, T. Rick Perche, Eduardo Martín-Martínez
We analyse the interaction between two quantum systems in spacetime and we compare two possible models to describe it: 1) a fully quantum field theoretical (QFT) description of the…
A relativistic QFT description for the interaction of a spin with a magnetic field
Ruhi Shah, Eduardo Martín-Martínez, T. Rick Perche
We analyze how non-relativistic effective models for the magnetic coupling of a spin to the electromagnetic field (proportional to ) emerge…
The stress-energy tensor of an Unruh-DeWitt detector
T. Rick Perche, J. P. M. Pitelli, Daniel A. T. Vanzella
We propose a model for a finite-size particle detector, which allows us to derive its stress-energy tensor. This tensor is obtained from a covariant Lagrangian that describes not o…
A Universal Quantum Computer From Relativistic Motion
Philip A. LeMaitre, T. Rick Perche, Marius Krumm +1
We present an explicit construction of a relativistic quantum computing architecture using a variational quantum circuit approach that is shown to allow for universal quantum compu…
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…
