Traps

abstract: We demonstrate Rabi flopping at MHz rates between ground hyperfine states of
neutral $^{87}$Rb 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 $8~\mu\rm m$ at
the level of $10^{-3}$. Ramsey spectroscopy is used to measure a dephasing time
of $870~\mu\rm s$ which is $\approx$~5000 times longer than the time for a
$\pi/2$ pulse.
