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…

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…

Indefinite causal order and quantum coordinates

Anne-Catherine de la Hamette, Viktoria Kabel, Marios Christodoulou +1

Classically the causal order of two timelike separated events A and B is fixed -- either A before B or B before A. This is no longer true in quantum theory, where it is possible to…

Quantum reference frames for an indefinite metric

Anne-Catherine de la Hamette, Viktoria Kabel, Esteban Castro-Ruiz +1

The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a str…

Entanglement-asymmetry correspondence for internal quantum reference frames

Anne-Catherine de la Hamette, Stefan L. Ludescher, Markus P. Mueller

In the quantization of gauge theories and quantum gravity, it is crucial to treat reference frames such as rods or clocks not as idealized external classical relata, but as interna…

Perspective-neutral approach to quantum frame covariance for general symmetry groups

Anne-Catherine de la Hamette, Thomas D. Galley, Philipp A. Hoehn +2

In the absence of external relata, internal quantum reference frames (QRFs) appear widely in the literature on quantum gravity, gauge theories and quantum foundations. Here, we ext…
