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…
Quantum Sensing of Gravitational Frame-Dragging with a Superfluid He Gyrometer
Kai-Isaak Ellers, Marios Christodoulou, K. C. Schwab +1
We propose a laboratory-scale experiment to locally measure the general relativistic frame-dragging effect on Earth using the macroscopic quantum properties of a novel superfluid $…
Evidencing Quantum Gravity with Thermodynamical Observables
Thomas Strasser, Marios Christodoulou, Richard Howl +1
Proposed experiments for obtaining empirical evidence for a quantum description of gravity in a table-top setting focus on detecting quantum information signatures, such as entangl…
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…
