Quantum dynamics simulations can be improved using novel quasiprobability
distributions based on non-orthogonal hermitian kernel operators. This
introduces arbitrary functions (gauges) into the stochastic equations, which
can be used to tailor them for improved calculations. A possible application to
full quantum dynamic simulations of BEC's is presented.
