Scaling up atom arrays

Atom arrays are a promising platform for scalable, programmable bottom-up control of individual qubits for quantum information science and metrology. In this talk, I will discuss the limits to scaling up atom arrays and present a solution involving tweezers set to 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. We demonstrate with our new technique an order-of-magnitude increase in scaling up sodium atom arrays, achieved by using D1 magic wavelength tweezers to trap and image single atoms at low trap depths without having to modulate the trapping and imaging light intensities. I will also discuss different routes to inducing programmable interactions between the singly trapped particles, with an outlook on using the assembled arrays as quantum simulators.
