Autonomization of Quantum Systems and the Emergence of the Work Operator
Carlo Cepollaro, Danial Chughtai, Alberto Spalvieri +2
Estimation of work at the quantum scale remains a central challenge in quantum thermodynamics. Canonical approaches have a fundamental drawback: they assume classical control of th…
The classical limit of quantum mechanics through coarse-grained measurements
Fatemeh Bibak, Carlo Cepollaro, Nicolás Medina Sánchez +2
Understanding how classical physics emerges from quantum mechanics remains a central problem in the foundations of physics. Here we derive a classical limit from finite-resolution…
Particle detector in a position-superposed black hole spacetime
Laurens Walleghem, Carlo Cepollaro
We calculate the response of an Unruh--DeWitt detector in a 2+1d spacetime that contains a BTZ black hole in a superposition of locations. Upon performing a Quantum Reference Frame…
Aumann's theorem beyond ontology: quantum, postquantum, and indefinite causal order
Carlo Cepollaro, Andrea Di Biagio
Agreement theorems are no-go results about rational disagreement: if two agents start from a common prior and their posterior beliefs are common knowledge, they cannot assign diffe…
The sum of entanglement and subsystem coherence is invariant under quantum reference frame transformations
Carlo Cepollaro, Ali Akil, PaweÅ CieÅliÅski +2
Recent work on quantum reference frames (QRFs) has demonstrated that superposition and entanglement are properties that change under QRF transformations. Given their utility in qua…
Identification is Pointless: Quantum Coordinates, Localisation of Events, and the Quantum Hole Argument
Viktoria Kabel, Anne-Catherine de la Hamette, Luca Apadula +4
The study of quantum reference frames (QRFs) is motivated by the idea of taking into account the quantum properties of the reference frames used, explicitly or implicitly, in our d…
