We report on the recent progress of the MQV quantum computing demonstrator based on neutral Sr atoms trapped in arrays of optical tweezers. We have shown high-fidelity detection, single- and two-qubit operations as well as state-of-the-art vacuum-limited lifetime in a non-cryogenic platform. We further present our ongoing work on the realization of highly parallel atom moves, setting the stage for future implementations of brickwall-type digital circuits.
