Experimental test of high-dimensional quantum contextuality based on contextuality concentration
(American Physical Society, 2023-06-13)
Contextuality is a distinctive feature of quantum theory and a fundamental resource for quantum computation. However, existing examples of contextuality in high-dimensional systems lack the necessary robustness required ...

Quantum contextuality provides communication complexity advantage
(American Physical Society, 2023-02-24)
Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we show that for any quantum state and observables ...

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, ...
