Duke and IonQ Achieve Three-Node Quantum Entanglement with Trapped Atomic Ions
By
Mohamed Abdel-Kareem
Summary
Researchers from Duke Quantum Center and IonQ have successfully demonstrated the distributed generation of a Greenberger–Horne–Zeilinger (GHZ) state — a form of tripartite quantum entanglement — across a three-node quantum network using trapped atomic ions. The experiment used three spatially separated hardware modules positioned about 2 meters apart, linked by 3-meter optical fiber connections. This achievement represents a significant step toward distributed quantum computing, where multiple smaller quantum processors can be networked together to solve problems beyond the capability of individual systems.
