Knot invariants and indefinite causal order
Samuel Fedida, Anne-Catherine de la Hamette, Viktoria Kabel +1
We explore indefinite causal order between events in the context of quasiclassical spacetimes in superposition. We introduce several new quantifiers to measure the degree of indefi…
Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
Hawking radiation for detectors in superposition of locations outside a black hole
Jerzy Paczos, Luis C. Barbado
Hawking radiation is the proposed thermal black-body radiation of quantum nature emitted from a black hole. One common way to give an account of Hawking radiation is to consider a…
Quantum Reference Frames at the Boundary of Spacetime
Viktoria Kabel, Časlav Brukner, Wolfgang Wieland
An analysis is given of the local phase space of gravity coupled to matter to second order in perturbation theory. Working in local regions with boundaries at finite distance, we i…
Metriplectic geometry for gravitational subsystems
Viktoria Kabel, Wolfgang Wieland
In general relativity, it is difficult to localise observables such as energy, angular momentum, or centre of mass in a bounded region. The difficulty is that there is dissipation.…
Measuring space-time curvature using maximally path-entangled quantum states
Thomas B. Mieling, Christopher Hilweg, Philip Walther
Experiments at the interface of quantum field theory and general relativity would greatly benefit theoretical research towards their unification. The gravitational aspects of quant…
