Quantum Permutations and Beyond Quantum Controlled Reference Frames
Ofek Bengyat, Časlav Brukner, Marios Christodoulou
Quantum permutations, or magic unitaries, have in recent years been explored in the context of identifying `genuinely quantum' isometries of graphs. Here, we import this tool in ph…
Complete Relational Description of Spin in a Quantum Background
Hannah Troger, Ofek Bengyat, Thomas D. Galley +1
The standard description of the state of a spin in quantum mechanics presupposes externally fixed directions -- a classical background. Can a spin be fully described instead in rel…
When does entanglement through gravity imply gravitons?
Nikolaos Mitrakos, Maria Papageorgiou, T. Rick Perche +1
Detection of entanglement through the Newtonian potential has been claimed to support the existence of gravitons, by extrapolating to a thought experiment which demonstrates that c…
Observables are glocal
Emil Broukal, Andrea Di Biagio, Eugenio Bianchi +1
We show that the problem of observables can be fully resolved for background independent theories defined on graphs, through the explicit construction of complete observables. The…
A truly relativistic gravity mediated entanglement protocol using superpositions of rotational energies
Gerard Higgins, Andrea Di Biagio, Marios Christodoulou
Experimental proposals for testing quantum gravity-induced entanglement of masses (QGEM) typically involve two interacting masses which are each in a spatial superposition state. H…
Gravity Mediated Entanglement between Oscillators as Quantum Superposition of Geometries
Ofek Bengyat, Andrea Di Biagio, Markus Aspelmeyer +1
Protocols for observing gravity induced entanglement typically comprise the interaction of two particles prepared either in a superposition of two discrete paths, or in a continuou…
