    "abstract": "We propose a novel approach toward the general solution of the sign problem\nin real-time path-integral simulations. Using a recursive multilevel blocking\nstrategy, this method circumvents the sign problem by synthesizing the phase\ncancellations arising from interfering quantum paths on multiple timescales. A\nnumber of numerical examples with one or a few explicit degrees of freedom\nillustrate the usefulness of the method.",
