Abstract

We determine a positive normalised phase space probability distribution PP with minimum mean square fractional deviation from the Wigner distribution WW .The minimum deviation, an invariant under phase space rotations, is a quantitative measure of the quantumness of the state.The positive distribution closest to WW will be useful in quantum mechanics and in time frequency analysis .
