State-independent quantum contextuality for continuous variables
arXiv:1005.1620 · doi:10.1103/PhysRevA.82.022114
Abstract
Recent experiments have shown that nature violates noncontextual inequalities regardless of the state of the physical system. So far, all these inequalities involve measurements of dichotomic observables. We show that state-independent quantum contextuality can also be observed in the correlations between measurements of observables with genuinely continuous spectra, highlighting the universal character of the effect.
