Comment on "Revisiting dynamics of quantum causal structures --when can causal order evolve?''
Esteban Castro-Ruiz, Flaminia Giacomini, Časlav Brukner
In the last few years, there has been increasing interest in quantum processes with indefinite causal order. Process matrices are a convenient framework to study such processes. Re…
Unruh effect for detectors in superposition of accelerations
Luis C. Barbado, Esteban Castro-Ruiz, Luca Apadula +1
The Unruh effect is the phenomenon that accelerated observers detect particles even when inertial observers experience the vacuum state. In particular, uniformly accelerated observ…
Quantum Temporal Superposition: the case of QFT
Laura J. Henderson, Alessio Belenchia, Esteban Castro-Ruiz +4
Quantum field theory is completely characterized by the field correlations between spacetime points. In turn, some of these can be accessed by locally coupling to the field simple…
