Physicists confirm 20-year-old theory that could boost quantum technology

Future quantum computing will require correlations between distant modules-a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists at the Institute of Science and Technology Austria (ISTA) have realized a fully autonomous method for distributed entanglement using a "quantum bath" of correlated light particles. Published in Physical Review X, their work experimentally confirms a 20-year-old predi...
