"based on 2D optical tweezer arrays created using focused laser beams... combines quantum-optics with micro-optics increasing current limits on accessible number of qubits... quantum bit supercharging overcomes restrictions imposed on number, by lasers' limited performance... 1,305 single-atom qubits loaded in quantum array with 3K trap sites and reassembled into defect-free target structures with up to 441 qubits... several laser sources in parallel enabled breakthrough technology... 10,000+ qubits in few years"
