Researchers from the Max Planck Institute of Quantum Optics (MPQ) and startup planqc have developed a quantum register of 1200 neutral atoms that can run continuously for over an hour. By adding roughly 130 atoms every 3.5 seconds, they maintain a stable atomic array, addressing a key challenge in scaling quantum systems. This innovation, which involves reloading atoms to counteract natural losses, could enable fault-tolerant quantum computing and long-duration simulations. The project is part of the Munich Quantum Valley Initiative and is funded by Bavarian and German federal agencies.
