Researchers from the Duke Quantum Center and IonQ have demonstrated the distributed generation of a Greenberger–Horne–Zeilinger (GHZ) state across a three-node quantum network using individual trapped atomic ions. The experimental configuration consisted of three spatially separated hardware modules positioned approximately 2 meters apart, linked by 3-meter single-mode optical fibers to a centralized, free-space GHZ-state generator.

This development represents a significant step in quantum network research, building on decades of theoretical work and recent advances in quantum hardware, pushing the limits of secure and distributed quantum computation.
Demonstrating entangled quantum states across physically separated nodes is crucial for scalable quantum computing architectures and the development of future quantum internet infrastructure, bypassing distance limitations in quantum communication.
This research moves distributed quantum entanglement from theoretical possibility to experimental realization over a non-trivial distance, suggesting a viable pathway for modular quantum processors and secure communication networks.
