Abstract
We study an implementation of a two-qubit universal quantum gate with neutral 87Rb atoms trapped in a far-detuned two-color optical lattice. The qubit states |Oć and |1ć represent the ground and first excited motional states of an atom in a laser induced potential well. By varying the ratio of the laser intensities of the two colors, the barrier between two neighboring atoms is lowered, creating two-particle entanglement. We predict the duration of operation of a conditional Ļ-phase gate with a time-dependent configuration interaction model.
