We formulate the time-dependent Bogoliubov dynamics of collidingBose-Einstein condensates in terms of a positive-P representation of theBogoliubov field. We obtain stochastic evolution equations for the field whichconverge to the full Bogoliubov description as the number of realisationsgrows. The numerical effort grows linearly with the size of the computationallattice. We benchmark the efficiency and accuracy of our description againstWigner distribution and exact positive-P methods. We consider its regime ofapplicability, and show that it is the most efficient method in the commonsituation - when the total particle number in the system is insufficient for atruncated Wigner treatment.
