2 ), where the Gaussian function is G(q, p) = 2 N +1 • exp[-N l=1 (q 2 l + p 2 l )]. In LSC-IVR, both operator Â and B in C AB (t) (Eq. 73) use the expression [|1 n 1 n |] w . For the closely related Poisson Bracket Mapping Equation (PBME), method, the choice of the operator Â is the same, but the estimator B is chosen to be [â †
