    "abstract": "The nonnegativity of the density operator of a state is faithfully coded in\nits Wigner distribution, and this places constraints on the moments of the\nWigner distribution. These constraints are presented in a canonically invariant\nform which is both concise and explicit. Since the conventional uncertainty\nprinciple is such a constraint on the first and second moments, our result\nconstitutes a generalization of the same to all orders. Possible application in\nquantum state reconstruction using optical homodyne tomography is noted.",
