IonQ has been awarded a contract under the Defense Advanced Research Projects Agency’s Heterogeneous Architectures for Quantum (HARQ) program to develop networked quantum computers that combine trapped‑ion, neutral‑atom, and superconducting qubits into a single interoperable system.
The award provides federal funding and validates IonQ’s quantum interconnect technology, which centers on quantum‑grade synthetic‑diamond memories designed for data‑center‑scale interconnects and long‑distance entanglement distribution. The contract positions IonQ to capture future defense and national‑security quantum contracts and strengthens its strategy of integrating quantum computing, networking, and cybersecurity into a unified ecosystem.
IonQ’s recent technical milestones— a 99.99% two‑qubit gate fidelity, the #AQ 64 milestone on its Tempo system, and the first field‑deployable qubit‑to‑photon frequency conversion— underpin the company’s capability to meet the HARQ program’s objectives and demonstrate the feasibility of heterogeneous quantum architectures.
Niccolo de Masi, Chairman and CEO of IonQ, said, “We’re pleased to be selected for DARPA’s HARQ program. IonQ’s pioneering quantum interconnect technology can enable modular scalability not only for ion traps, but for a wide range of quantum technologies. We look forward to collaborating with DARPA to strengthen national security by developing the quantum platform which can serve as a backbone for networking and scaling quantum systems—across qubit types—for advanced public and private sector applications.”
The announcement was well received by the market, with investors noting the strategic significance of the DARPA award and the broader momentum in quantum computing, including Nvidia’s related announcements on the same day.
