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…
Switching quantum reference frames in the N-body problem and the absence of global relational perspectives
Augustin Vanrietvelde, Philipp A. Hoehn, Flaminia Giacomini
Given the importance of quantum reference frames (QRFs) to both quantum and gravitational physics, it is pertinent to develop a systematic method for switching between the descript…
A change of perspective: switching quantum reference frames via a perspective-neutral framework
Augustin Vanrietvelde, Philipp A Hoehn, Flaminia Giacomini +1
Treating reference frames fundamentally as quantum systems is inevitable in quantum gravity and also in quantum foundations once considering laboratories as physical systems. Both…
Quantum Superposition of Massive Objects and the Quantization of Gravity
Alessio Belenchia, Robert M. Wald, Flaminia Giacomini +3
We analyse a gedankenexperiment previously considered by Mari et al. that involves quantum superpositions of charged and/or massive bodies ("particles") under the control of the ob…
Thermal and spectral dimension of (generalized) Snyder noncommutative spacetimes
Giovanni Amelino-Camelia, Flaminia Giacomini, Giulia Gubitosi
We report an investigation of the Snyder noncommutative spacetime and of some of its most natural generalizations, also looking at them as a powerful tool for comparing different n…
