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…
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 as viewed in a reference system associated…
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 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…
The sum of entanglement and subsystem coherence is invariant under quantum reference frame transformations
Carlo Cepollaro, Ali Akil, Paweł Cieśliński +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…
