Loophole-free Bell tests with randomly chosen subsets of measurement settings
(American Physical Society, 2024-02-06)
There are bipartite quantum nonlocal correlations requiring very low detection efficiency to reach the loophole-free regime but that need too many measurement settings to be practical for actual experiments. This leads to ...

Graph-theoretic approach to Bell experiments with low detection efficiency
(Cornell University, 2023)
Bell inequality tests where the detection efficiency is below a certain threshold ηcrit can be simulated with local hidden-variable models. For the Clauser-Horne-Shimony-Holt Bell inequality and maximally entangled states, ...
