Characterizing single atom optical dipole traps

Trapping and manipulating individual neutral atoms in far off-resonant traps (FORTs) is a promising approach for quantum information processing. It is important to characterize the trapping environment of the atom and the atomic level shifts due to the trapping fields. Using non-destructive measurement techniques,\footnote{M.~J.~Gibbons \textit{et al.}, \textit{Phys. Rev. Lett} \textbf{106}, 133002 (2011).} we have measured the level dependent AC Stark shifts, trap frequencies, and temperature of single rubidium atoms confined in optical dipole trap.
