Physicists Harness 13,000 Nuclear Spins to Unlock 'Dark State' Power
Physicists have entangled 13,000 nuclear spins in gallium arsenide quantum dots to create a stable 'dark state' for quantum information storage, advancing quantum network nodes and communication technology. This collective entanglement improves data retention and resistance to noise, paving the way for scalable quantum devices and long-distance quantum communication. The research highlights the potential of many-body physics in developing reliable quantum systems.
