Resumen | Quantum correlations are contextual yet, in general, nothing prevents the existence of even more
contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation
cannot be improved ... Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation cannot be improved by any hypothetical postquantum theory, and use it to experimentally obtain correlations in which the fraction of noncontextual correlations is less than 0.06. Our correlations are experimentally generated from the results of sequential compatible tests on a four-state quantum system encoded in the polarization and path of a single photon. |
