Rectangular Quantum Stochastic Webs

Classically, for $T=\pi /2$ ($q=4$) rectangular stochastic webs are obtained: cf. figures 1.7, 1.8, 1.10b and 1.12. The skeletons of these webs extend in the neighbourhood of the square grid given by equation (1.45). In the figures of the present section, this grid is displayed via thin lines, in addition to the contour lines of $F^{\rm H}(x,p,nT-0;1)$.
