    "abstract": "We provide a necessary and sufficient condition for separability of Gaussian\nstates of bipartite systems of arbitrarily many modes. The condition provides\nan operational criterion since it can be checked by simple computation.\nMoreover, it allows us to find a pure product-state decomposition of any given\nseparable Gaussian state. Our criterion is independent of the one based on\npartial transposition, and is strictly stronger.",
