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…
