    "abstract": "We investigate the inverse problem concerning the evolution of a qubit\nsystem, specifically we consider how one can establish the Hamiltonians that\naccount for the evolution of a qubit along a prescribed path in the projected\nHilbert space. For a given path, there are infinite Hamiltonians which can\nrealize the same evolution. A general form of the Hamiltonians is constructed\nin which one may select the desired one for implementing a prescribed\nevolution. This scheme can be generalized to higher dimensional systems.",
