Abstract
We use coherent excitation of 3-16 atom ensembles to demonstrate collective Rabi flopping mediated by Rydberg blockade. Using calibrated atom number measurements, we quantitatively confirm the expected sqrt{N} Rabi frequency enhancement to within 4%. The resulting atom number distributions are consistent with essentially perfect blockade. We then use collective Rabi π pulses to produce {cal N}=1,2 atom number Fock states with fidelities of 62% and 48% respectively. The {cal N}=2 Fock state shows the collective Rabi frequency enhancement without corruption from atom number fluctuations.
