Abstract
Recent papers by Khaneja, Brockett and Glaser obtained efficient RF pulse trains for two-spin and three-spin NMR systems by finding sub-Riemannian geodesics on a quotient space of SU(4). This paper outlines a method for extending their results via the Griffiths formalism for constrained variational problems.
