Temporal quantum correlations and Leggett-Garg inequalities in multi-level systems
Costantino Budroni, Clive Emary
We show that the quantum bound for temporal correlations in a Leggett-Garg test, analogous to the Tsirelson bound for spatial correlations in a Bell test, strongly depends on the n…
Bounding temporal quantum correlations
Costantino Budroni, Tobias Moroder, Matthias Kleinmann +1
Sequential measurements on a single particle play an important role in fundamental tests of quantum mechanics. We provide a general method to analyze temporal quantum correlations,…
Bounding the quantum dimension with contextuality
Otfried Gühne, Costantino Budroni, Adan Cabello +2
We show that the phenomenon of quantum contextuality can be used to certify lower bounds on the dimension accessed by the measurement devices. To prove this, we derive bounds for d…
