Neutral atom quantum computer of Cs atoms in a 5-$\mu$m spaced 3D optical lattice

POSTER

Abstract

We present an approach to quantum computing using laser-cooled single Cs atoms in a 5-$\mu$m spaced 3D optical lattice. Single qubit operations can be accomplished with a combination of ac-Stark shifting addressing beams and microwaves. Rapid steering of the lasers using micromirrors allows target atoms to be changed in tens of $\mu$s. Single-site addressing combined with lattice polarization rotation enables us to fill voids in the central region of the atom array by selectively moving individual atoms. We will also describe progress toward executing pairwise entanglement operations.
