IonQ is expanding its partnership with QuantumBasel. The agreement brings the total deal value to $60M+, extends IonQ’s on-site presence through 2029, grants ownership of IonQ Forte Enterprise, and secures ownership of a next-gen Tempo system. QuantumBasel remains IonQ’s European Innovation Center, advancing applied quantum computing across AI, materials, life sciences, and more. https://t.co/VqCxXRef3v #QuantumComputing #QuantumTechnology #Innovation #AI

$IonQ just got selected for DARPA’s Heterogeneous Architectures for Quantum (HARQ) program. Announced today. The mission: build a new class of networked quantum computers that combine different qubit types trapped ions, neutral atoms, superconducting qubits into one interconnected, high-performance architecture. Each modality contributes its strengths. The interconnect layer makes it possible. IonQ’s specific contribution: quantum memories the core chips around which IonQ’s quantum interconnect systems are built. Fabricated from quantum-grade synthetic diamond. Designed to support HARQ’s speed and fidelity targets, from datacenter-scale interconnects to long-distance entanglement distribution networks. De Masi’s framing: “IonQ’s pioneering quantum interconnect technology can enable modular scalability not only for ion traps, but for a wide range of quantum technologies.” Two 2025 results IonQ explicitly ties to this selection: → 99.99% two-qubit gate fidelity (world record) → #AQ 64 milestone on IonQ Tempo, three months ahead of schedule → First qubit-to-photon frequency conversion in a field-deployable system meaning quantum networks can run on existing standard fiber optic commercial infrastructure Connections worth noting: → The diamond memory chips are exactly the technology we covered when Lightsynq (acquired June 2025) demonstrated 1.55 km entanglement-assisted interferometry in Nature, and again when the Element Six × Lightsynq × AWS wafer-scale diamond membrane paper was “Featured in Physics” in Phys. Rev. X. The HARQ contract is that lab work going operational. → As we covered yesterday with the QLab expansion UMD will deploy IonQ’s first silicon vacancy (SiV) quantum memory node on the MARQI network. Same memory architecture family. University testbed on one side, DARPA program on the other. → As we covered with Mihir Bhaskar (SVP R&D, ex-Lightsynq CEO) and Bart Machielse (Director of Photonics) at Harvard SEAS these are the people who will execute HARQ inside IonQ. → DARPA already advanced IonQ to the second stage of the Quantum Benchmarking Initiative (QBI) in November 2025. HARQ is a separate program. Two parallel DARPA tracks running on IonQ hardware now. The strategic point: HARQ isn’t asking who has the most qubits. It’s asking who can connect different qubit types into one system. IonQ just got picked to build the connective tissue using diamond memories from an acquisition that’s barely 10 months old. 🔗 https://t.co/WwnuKAbVIF $IONQ #IonQ #DARPA #QuantumNetworking
