# Arbitrarily large violations of non-contextuality in single mode photon states with positive Wigner function. (arXiv:1807.02762v4 [quant-ph] UPDATED)

Banaszek, W\'odkiewicz and others
squeezed vacuum by a factor $\sqrt{2}$, in spite of the fact that the state has
derive non-contextuality Bell inequalities for correlations of $N$ pseudo spins
