    "abstract": "A simple theoretical solution to the design of a control field that generates\ncomplete population transfer from an initial state, via $N$ nondegenerate\nintermediate states, to one arbitrary member of $M$ ($M\\leq N$) degenerate\nstates is constructed. The full control field exploits an $(M+N-1)$-node null\nadiabatic state, created by designing the relative phases and amplitudes of the\ncomponent fields that together make up the full field. The solution found is\nuniversal in the sense that it does not depend on the exact number of the\nunwanted degenerate states or their properties. The results obtained suggest\nthat a class of multi-level quantum systems with degenerate states can be\ncompletely controllable, even under extremely strong constraints, e.g., never\npopulating a Hilbert subspace that is only a few dimensions smaller than the\nwhole Hilbert space.",
