Paper Abstract

Four atomic optical energy levels is proposed to use as a two qubit quantum register. A single Pr3+ atom in a monocrystal LaF3 subjected to resonant laser irradiation is used as an example to illustrate the implementation of the universal set of quantum gates. This physical system equilibrium state is a desirable input state for quantum computation and therefore there is no need for its special preparation procedure.
