    "abstract": "We consider the problem of carrying an initial Bloch vector to a final Bloch\nvector in a specified amount of time under the action of three control fields\n(a vector control field). We show that this control problem is solvable and\ntherefore it is possible to optimize the control. We choose the physically\nmotivated criteria of minimum energy spent in the control, minimum magnitude of\nthe rate of change of the control and a combination of both. We find exact\nanalytical solutions.",
