AQuA: A 2D array of Rydberg coupled atomic qubits

POSTER

Abstract

We are developing a 2D array of optically trapped single atom qubits for quantum computation experiments. We demonstrate stochastic loading of an average of 30 Cs atom qubits in a 49 site array with 3.8 $\mu\rm m$ site to site spacing. Parallel qubit rotations are performed with microwaves and site selective single qubit gates are demonstrated using focused beams of two-frequency Raman light. Single qubit gate fidelity is characterized with randomized benchmarking. Using Rydberg excitation and blockade we demonstrate conditional phase shifts of pairs of trapped atoms and will report on progress towards running quantum algorithms in the array.
