Abstract
Numerical and experimental realizations of quantum control are closely connected to the properties of the mapping from the control to the unitary propagator Rabitz et al in Science 30356661998–2001 2004 For bilinear quantum control problems no general results are available to fully determine when this mapping is singular or not In this paper we give sufficient conditions in terms of elements of the evolution semigroup for a trajectory to be nonsingular We identify two lists of “waypoints” that when reached ensure the nonsingularity of the control trajectory It is found that under appropriate hypotheses one of those lists does not depend on the values of the coupling operator matrix
