An Operational Resolution of the Third-Particle Paradox
Äaslav Brukner, Esteban Castro-Ruiz, Marius Krumm
We give an operational resolution of the third-particle paradox, relevant in the theory of quantum reference frames. The apparent paradox is that a system which is irrelevant in on…
Quantum incompatibility of Born probabilities
Esteban Castro-Ruiz, Nathan Cohen, Luis C. Barbado +1
The paper shows that when measurements are performed relative to non‑ideal quantum reference frames, the Born probabilities become indefinite, leading to irreducible uncertainty in…
The Perspectives of Non-Ideal Quantum Reference Frames
Sébastien Christophe Garmier, Ladina Hausmann, Esteban Castro-Ruiz
We define the perspective of any quantum reference frame (QRF) and construct reversible transformations between different perspectives. Our construction is based on two principles…
Quantum limits of a space-time reference frame
Davide Mattei, Esteban Castro-Ruiz
We study the limitations for defining spatial and temporal intervals when the only available reference frame is a single composite quantum system, whose internal degrees of freedom…
Interpreting quantum reference frame transformations through a simple example
Esteban Castro-Ruiz, Thomas D. Galley, Leon Loveridge
Quantum reference frame transformations have been proposed to provide a means by which to translate descriptions of quantum systems relative to each other. At present, there are se…
Measurement events relative to temporal quantum reference frames
Ladina Hausmann, Alexander Schmidhuber, Esteban Castro-Ruiz
The Page-Wootters formalism is a proposal for reconciling the background-dependent, quantum-mechanical notion of time with the background independence of general relativity. Howeve…
