Existing experiments suffice to indirectly verify the quantum essence of gravity
Martin Plávala
The gravity-mediated entanglement experiments employ concepts from quantum information to argue that if entanglement due to gravitational interaction is observed, then gravity cann…
Ruling out nonlinear modifications of quantum theory with contextuality
Ruben Campos Delgado, Martin Plávala
Nonlinear modifications of quantum theory are considered potential candidates for the theory of quantum gravity, with the intuitive argument that since Einstein field equations are…
Probing the nonclassical dynamics of a quantum particle in a gravitational field
Martin Plávala, Stefan Nimmrichter, Matthias Kleinmann
In quantum mechanics, the time evolution of particles is given by the Schrödinger equation. It is valid in a nonrelativistic regime where the interactions with the particle can be…
Experimental implementation of dimension-dependent contextuality inequality
Emil Håkansson, Amelie Piveteau, Alban Seguinard +4
We present a derivation and experimental implementation of a dimension-dependent contextuality inequality to certify both the quantumness and dimensionality of a given system. Exis…
