    • Note that the problem of testing for mixed states is considerably more difficult. Not every normalized function on phase space corresponds to a legitimate mixed or pure quantum state, and there is no simple way of determining whether a given function does in fact correspond to a state. The problem is equivalent to determining whether a given Hermitian matrix with unit trace has no negative eigenvalues, i.e., whether it is a legitimate density matrix.
