    "abstract": "We present new results on the quantum control of systems with infinitely\nlarge Hilbert spaces. A control-theoretic analysis of the control of trapped\nion quantum states via optical pulses is performed. We demonstrate how resonant\nbichromatic fields can be applied in two contrasting ways -- one that makes the\nsystem completely uncontrollable, and the other that makes the system\ncontrollable. In some interesting cases, the Hilbert space of the\nqubit-harmonic oscillator can be made finite, and the Schr\\\"{o}dinger equation\ncontrollable via bichromatic resonant pulses. Extending this analysis to the\nquantum states of two ions, a new scheme for producing entangled qubits is\ndiscovered.",
