Abstract

We demonstrate Rabi flopping at MHz rates between ground hyperfine states of neutral ⁸⁷Rb atoms that are trapped in two micron sized optical traps. Using tightly focused laser beams we demonstrate high fidelity, site specific Rabi rotations with crosstalk on neighboring sites separated by 8 μ\rm m at the level of 10^-3. Ramsey spectroscopy is used to measure a dephasing time of 870 μ\rm s which is ≈ 5000 times longer than the time for a π/2 pulse.
