Compositionality in quantum reference frame perspectives
Bruna Sahdo, Esteban Castro-Ruiz
Understanding a composite system through its constituents is a fundamental practice in physics. In the context of quantum reference frames (QRFs), however, combining the usual quan…
An Operational Resolution of the Third-Particle Paradox
Časlav 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
Quantum theory challenges the view that individual measurement outcomes are predefined and independent of the measurement context. Yet the quantum state itself -- the catalogue of…
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…
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…
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…
