Query: Quantum Stratonovich Stochastic Calculus and the Quantum Wong-Zakai
  Theorem   We extend the Ito -to- Stratonovich analysis or quantum stochastic
differential equations, introduced by Gardiner and Collett for emission
(creation), absorption (annihilation) processes, to include scattering
(conservation) processes. Working within the framework of quantum stochastic
calculus, we define Stratonovich calculus as an algebraic modification of the
Ito one and give conditions for the existence of Stratonovich time-ordered
exponentials. We show that conversion formula for the coefficients has a
striking resemblance to Green's function formulae from standard perturbation
theory. We show that the calculus conveniently describes the Markov limit of
regular open quantum dynamical systemsin much the same way as in the Wong-Zakai
approximation theorems of classical stochastic analysis. We extend previous
limit results to multiple-dimensions with a proof that makes use of
diagrammatic conventions.
