  • IonQ announced that it has achieved the second milestone in its photonic‑interconnect roadmap: remote entanglement between two ion qubits in a commercial setting. This follows the company’s February 2024 success in entangling a single photon with an ion qubit (Milestone 1). The new demonstration uses entangled photons to link separate quantum‑processing units (QPUs), enabling qubits to be entangled across distinct processors. IonQ’s modular architecture relies on these photonic links to scale quantum computing power, with the goal of building large‑scale, networked QPU systems. The milestone marks a key step toward commercially viable quantum networking.
