Quantum reference frames beyond subsystems: a reconstruction and generalization of the perspective-neutral framework
Stefan L. Ludescher, Manuel Mekonnen, Thomas D. Galley +1
We generalize the notion of quantum reference frames (QRFs) to cases where the frame does not necessarily correspond to a tensor factor subsystem, but to a covariant quantum instru…

Gravity-mediated entanglement via infinite-dimensional systems
Stefan L. Ludescher, Leon D. Loveridge, Thomas D. Galley +1
There has been a wave of recent interest in detecting the quantum nature of gravity with table-top experiments that witness gravitationally mediated entanglement. Central to these…

Spin-bounded correlations: rotation boxes within and beyond quantum theory
Albert Aloy, Thomas D. Galley, Caroline L. Jones +2
How can detector click probabilities respond to spatial rotations around a fixed axis, in any possible physical theory? Here, we give a thorough mathematical analysis of this quest…
