The random variables are quantum waves in the complex vector without being defined for Cauchy-Schwartz inequality. Decoherence is giving the variables real numbers for position and momentum which voids Cauchy-Schwartz (Uncertainty).
QM mathematical objects have random variables when not specifically defined.
The second instance of decoherence in the quantum which-way eraser is the particle getting negative correlation again.
