Optimal and tight Bell inequalities for state-independent contextuality sets
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Two fundamental quantum resources, nonlocality and contextuality, can be connected through Bell inequalities that are violated by state-independent contextuality (SI-C) sets. These Bell inequalities allow for applications requiring simultaneous nonlocality and contextuality. For existing Bell inequalities, the nonlocality produced by SI-C sets is very sensitive to noise. This precludes actual experiments. Here, we identify the Bell inequalities for which the nonlocality produced by SI-C sets is optimal, i.e., maximally robust to either noise or detection inefficiency, for the simplest SI-C [S. Yu and C. H. Oh, Phys. Rev. Lett. 108, 030402 (2012)] and Kochen-Specker sets [A. Cabello et al., Phys. Lett. A 212, 183 (1996)] and show that, in both cases, nonlocality is sufficiently resistant for experiments.
