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…

The Generalized Skew Spectrum of Graphs
Armando Bellante, Martin Plávala, Alessandro Luongo
This paper proposes a family of permutation-invariant graph embeddings, generalizing the Skew Spectrum of graphs of Kondor & Borgwardt (2008). Grounded in group theory and harmonic…

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…
