    "abstract": "It is proposed to use four atomic optical energy levels as a two qubit\nquantum register. A single Pr3+ atom in a monocrystal LaF3 subjected to\nresonant laser irradiation is used as an example to illustrate the\nimplementation of the universal set of quantum gates. The equilibrium state of\nthis physical system is a desirable input state for quantum computation and\ntherefore there is no need for its special preparation procedure.",
