New and improved bounds on the contextuality degree of multi-qubit configurations

Axel Muller, Metod Saniga, Alain Giorgetti +2

We present algorithms and a C code to reveal quantum contextuality and evaluate the contextuality degree (a way to quantify contextuality) for a variety of point-line geometries lo…

A new heuristic approach for contextuality degree estimates and its four- to six-qubit portrayals

Axel Muller, Metod Saniga, Alain Giorgetti +2

We introduce and describe a new heuristic method for finding an upper bound on the degree of contextuality and the corresponding unsatisfied part of a quantum contextual configurat…

Hexagons govern three-qubit contextuality

Metod Saniga, Frédéric Holweck, Colm Kelleher +3

Split Cayley hexagons of order two are distinguished finite geometries living in the three-qubit symplectic polar space in two different forms, called classical and skew. Although…

Mass Testing and Characterization of 20-inch PMTs for JUNO

Angel Abusleme, Thomas Adam, Shakeel Ahmad +556

Main goal of the JUNO experiment is to determine the neutrino mass ordering using a 20kt liquid-scintillator detector. Its key feature is an excellent energy resolution of at least…

Multi-qubit doilies: enumeration for all ranks and classification for ranks four and five

Axel Muller, Metod Saniga, Alain Giorgetti +2

For , an -qubit doily is a doily living in the -qubit symplectic polar space. These doilies are related to operator-based proofs of quantum contextuality. Following…

An abstract structure determines the contextuality degree of observable-based Kochen-Specker proofs

Axel Muller, Alain Giorgetti

This article delves into the concept of quantum contextuality, specifically focusing on proofs of the Kochen-Specker theorem obtained by assigning Pauli observables to hypergraph v…
