Qudit Clauser-Horne-Shimony-Holt Inequality and Nonlocality from Wigner Negativity
Uta Isabella Meyer, Ivan Šupić, Damian Markham +1
Nonlocality is an essential concept that distinguishes quantum from classical models and has been extensively studied in systems of qubits. For higher-dimensional systems, certain…

Self-Testing Graph States Permitting Bounded Classical Communication
Uta Isabella Meyer, Ivan Šupić, Frédéric Grosshans +1
Self-testing identifies quantum states and correlations that exhibit nonlocality, distinguishing them, up to local transformations, from other quantum states. Due to their strong n…
