IonQ and SDT Expand Quantum Hardware Partnership

The agreement broadens IonQ and SDT’s existing relationship beyond cloud-based quantum software integration. Both companies will now work on hardware manufacturing, assembly, system integration, and regional commercial deployment. The expanded partnership also strengthens IonQ’s physical infrastructure presence within South Korea.

IonQ plans to supply SDT with its Superion 256 quantum computing system. SDT will deploy the system with one of its customers in South Korea. Both companies also plan to develop a hybrid quantum-classical data center around the deployment.

The partnership includes IonQ’s silicon-vacancy quantum memory technology for future quantum networking applications. SDT will support packaging, manufacturing, assembly, and commissioning work through its planned Korean facility. These activities could strengthen IonQ’s regional supply chain and hardware delivery capacity.

SDT Plans Quantum Manufacturing Facility in Gumi

SDT plans to establish a dedicated quantum manufacturing and system-integration facility in Gumi, South Korea. The site will handle parts of IonQ’s quantum memory packaging and manufacturing operations. It will also support system assembly, integration, testing, and commissioning activities.

SDT intends to build broader manufacturing capabilities through its work with IonQ. The company plans to participate directly in quantum system assembly and operating activities. It also expects to pursue opportunities involving additional quantum components and infrastructure.

The companies will also support a separate cancer research project inside South Korea. That effort will combine classical computing systems with IonQ’s quantum technology for biomedical research. The project extends the partnership beyond commercial computing into medical and scientific applications.

IonQ Expands Its South Korea Quantum Footprint

IonQ already maintains several research and commercial relationships across South Korea. Its partners include KISTI, SK Telecom, Hyundai Motor Company, and major Korean universities. These agreements cover quantum computing, networking, high-performance computing, and advanced research applications.

IonQ has also worked with Seoul National University and Sungkyunkwan University on quantum research programs. Those academic relationships have helped expand the company’s presence within South Korea’s developing quantum ecosystem. The SDT agreement adds manufacturing and system deployment capabilities to that existing network.

IonQ develops quantum computing, networking, sensing, security, and related infrastructure through its full-stack technology platform. The company previously reported 99.99% two-qubit gate fidelity during 2025. Its systems have also supported projects involving AWS, AstraZeneca, NVIDIA, and other technology organizations.
