Abstract: The optimal transport problem studied by Monge (1781) and Kantorovich (1942) provides a general method for metrizing the set of Borel probability measures on . The purpose of this talk is to present an analogous method for comparing density operators on , which are the quantum mechanical analogues of probability measures on the phase space . We shall discuss some properties of the ``pseudo-distance’’ on quantum states obtained in this way, and show applications to some problems in quantum dynamics. (Based on joint works with E. Caglioti, C. Mouhot, T. Paul).
