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…
Quantum clocks and the temporal localisability of events in the presence of gravitating quantum systems
Esteban Castro-Ruiz, Flaminia Giacomini, Alessio Belenchia +1
The standard formulation of quantum theory relies on a fixed space-time metric determining the localisation and causal order of events. In general relativity, the metric is influen…
Information Content of the Gravitational Field of a Quantum Superposition
Alessio Belenchia, Robert M. Wald, Flaminia Giacomini +3
When a massive quantum body is put into a spatial superposition, it is of interest to consider the quantum aspects of the gravitational field sourced by the body. We argue that in…
Relativistic quantum reference frames: the operational meaning of spin
Flaminia Giacomini, Esteban Castro-Ruiz, Časlav Brukner
The spin is the prime example of a qubit. Encoding and decoding information in the spin qubit is operationally well defined through the Stern-Gerlach set-up in the non-relativistic…
