A “quantum bath” puts quantum entanglement on autopilot
AI Summary: Physicists at the Institute of Science and Technology Austria demonstrated a fully autonomous method for creating distributed entanglement between separated qubits using a "quantum bath" made from correlated particles of light. This approach, published in Physical Review X, experimentally realized a prediction proposed over 20 years ago and could offer a new foundation for practical quantum technologies. The method uses a shared source of correlated light particles to entangle two separated qubits, stabilizing the entangled state without requiring active control or measurement. The entangled state remains available as a resource for further quantum processing, even beyond the qubits' own lifetime.
