Improved 3,000-qubit neutral atom array system reloads atoms continuously for more than two hours, preserving info even as atoms replaced

"typically arrange neutral atoms like rubidium using optical tweezers, held under vacuum, used as qubits, but results in some atoms lost from entangling operation errors, state-readout, finite trap lifetime, necessitating performance limiting pulsed operation... overcome using dual optical lattice conveyor belt–like system transporting cold atoms into optical tweezers at 300K/ sec. reloading rate, then 30K qubits/ sec. continuously replenishing 3K-atom array... future: 5X faster, scalable to 10s of thousands atomic qubits"
