Atomic Fock State Preparation Using Rydberg Blockade
Atomic Fock State Preparation Using Rydberg Blockade
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 an essentially perfect blockade. We then use collective …
