Duke and IonQ entangle three remote trapped-ion nodes into a GHZ state
Researchers at the Duke Quantum Center and IonQ report distributed generation of a three-qubit Greenberger–Horne–Zeilinger state across a three-node network of individual trapped atomic ions. The modules sat roughly 2 metres apart, linked by 3-metre single-mode fibers to a centralized free-space GHZ generator — a concrete step toward multi-node trapped-ion quantum networking.
