An extended Wigner's friend no-go theorem inspired by generalized contextuality
Laurens Walleghem, Lorenzo Catani
The renowned Local Friendliness no-go theorem demonstrates the incompatibility of quantum theory with the combined assumptions of Absoluteness of Observed Events - the idea that ob…
Resource-theoretic hierarchy of contextuality for general probabilistic theories
Lorenzo Catani, Thomas D. Galley, Tomáš Gonda
In this work we present a hierarchy of generalized contextuality. It refines the traditional binary distinction between contextual and noncontextual theories, and facilitates their…
First-Click Time Measurements
Mafalda Pinto Couto, Lorenzo Maccone, Lorenzo Catani +1
There are two distinct perspectives on the quantum time-of-arrival: one can ask for the probability that a particle is found at the detector at a given time, regardless of whether…
Experimental investigation of nonclassicality in the simplest scenario via the degrees of freedom of light
João M. M. Gama, Guilherme T. C. Cruz, Massy Khoshbin +3
In this work, we experimentally investigate the classical-light emulation of different notions of nonclassicality in the simplest scenario. We implement this prepare-and-measure sc…
