Oxford physicists have demonstrated quantum entanglement between strontium and calcium atoms across separate network locations. By combining different elements, the team created shared quantum states involving up to four atoms and used calcium to preserve the entanglement for over 10 seconds. Published in Physical Review Letters, this breakthrough offers a foundation for distributed quantum computing, remote sensing, and precision timekeeping.
