Within the QRydDemo project, aiming to realize a Rydberg atom quantum computer using strontium, we develop fully dynamic optical tweezer platforms. For our primary array we employ an all electro-optical setup containing 20 Acousto-Optic Deflectors (AODs), where each AOD can be driven by up to 100 tones and row spacing is achieved using a three-staged step mirror. This allows us to generate 2D arrays with an unprecedented dynamical connectivity reminiscent of an abacus. Through shuffling operations on a timescale of the qubit coherence time, atoms can be rearranged into various geometries. This allows for fast sorting as well as rearrangement during the algorithm, enabling error correction by physical movement using a dedicated feedback-loop. To extend the qubit architecture, we aim to realize a fully bichromatic array enabling processing and storage in a dual-qubit setting, where the second array will be generated using a phase-only spatial light modulator with fast frame rates.
