Abstract

Reconfigurable atom arrays are a promising platform for the scalable control of individual qubits for quantum computation and simulation. In this talk, the speaker will discuss the limits to scaling up atom arrays and present a solution involving the operation of tweezers at a D1 magic wavelength. Unlike D2 magic wavelengths that only exist for cesium, D1 magic wavelengths have been predicted to exist for all the alkali atoms but are not yet observed to date. She will report an order-of-magnitude increase in scaling up sodium atom arrays with her new technique. She will also present her recent results on achieving defect-free arrays of hundreds of atoms on a second experiment. Finally, she will briefly discuss different routes to inducing programmable interactions between the singly-trapped particles with an eye towards future quantum simulation experiments.
