Deployment will bring the first IonQ Superion 256 system and first silicon-vacancy quantum memory module to South Korea

SEOUL, Republic of Korea & COLLEGE PARK, Md.--(BUSINESS WIRE)-- IonQ (NYSE: IONQ), the world’s leading full-stack quantum platform and foundry, today announced a strategic partnership with Korea-based quantum technology and software company SDT, Inc. Under this multi-year collaboration IonQ will supply SDT with a Superion 256 quantum computer as well as IonQ’s silicon-vacancy (SiV) quantum memory module.

"Demand for our new Superion 256 system is growing globally, and this agreement in Asia Pacific is yet another example of our clients combining IonQ’s leading quantum computers with our quantum networking and quantum memory solutions," said Niccolo de Masi, Chairman and CEO of IonQ. “IonQ is very proud to be expanding our commercial footprint in South Korea as well as continuing to trailblaze quantum cancer and biomedical research. This purchase equips SDT with the building blocks for both high-performance quantum computing and quantum data centers of the future.”

The partnership expands the two companies' ongoing collaboration from cloud-based software integration to physical hardware production, assembly, and regional resale partnership. The Superion 256 system is planned for deployment with an SDT customer in South Korea, where IonQ and SDT intend to collaborate on a hybrid quantum-classical data center. SDT also plans to establish a dedicated quantum manufacturing and system-integration facility in Gumi, South Korea. That will be the site for IonQ’s SiV quantum memory packaging and manufacturing, quantum system assembly, integration and commissioning.

"IonQ leads the global quantum industry in both technology and manufacturing innovation," said Jiwon Yune, CEO of SDT. "Our objective is to make our new Gumi facility a key operational hub for IonQ’s global supply chain and regional deployment by hosting manufacturing operations and assembling world-class quantum systems. Alongside this manufacturing partnership, SDT will participate in the assembly and operation of IonQ quantum systems and actively pursue opportunities to manufacture more quantum components. Our role will also extend to a separate in-country cancer center project where we intend to develop hybrid quantum-classical infrastructure for medical and biomedical research with IonQ. Together, these initiatives put SDT’s quantum design and manufacturing strategy into practice through assembly, operations and system integration, while opening opportunities in manufacturing and regional commercialization."

This announcement reinforces IonQ’s regional commitment as evidenced through its collaborations with other partnerships in Korea including: KISTI, SK Telecom, Hyundai Motor Company, and leading academic institutions such as Seoul National University and Sungkyunkwan University.

Key Terms

silicon-vacancy technical

A silicon-vacancy is a specific atomic defect inside a crystal—most commonly a diamond—where a silicon atom sits next to a missing carbon atom. It acts like a tiny, controllable light-and-electron source with stable optical and quantum properties, useful for quantum computing, secure communications, and advanced sensors; investors should note it as a core enabling material that can determine the performance and commercial potential of quantum and photonics products.

quantum memory technical

Quantum memory is a device or material that stores information encoded in quantum states, such as the orientation or phase of individual atoms, photons, or electron spins, and later releases that information without destroying its fragile quantum properties. It matters to investors because it is a core enabling component for quantum communication, quantum computing, and secure networks—like a computer hard drive for quantum bits—so its performance affects the viability and commercial timing of related technologies.

quantum networking technical

Quantum networking uses principles of quantum physics to connect devices so they can share and synchronize information in ways that classical networks cannot, often enabling extremely strong security and coordination. For investors it matters because it promises new layers of telecom and cybersecurity infrastructure, potential breakthroughs in computing and sensors, and long-term market opportunities and risks as companies race to build the underlying hardware and services — like betting on a new type of highway before cars evolve to use it.

hybrid quantum-classical technical

A hybrid quantum-classical system pairs a quantum processor, which can perform certain types of complex calculations using quantum bits, with a conventional computer that runs ordinary software and coordinates the workflow. For investors it matters because this mixed approach is the most practical route to real-world gains from quantum computing: like using a specialist for the hardest plays while the rest of the team handles routine work, it can speed up specific tasks (optimization, simulation, cryptography) that may create new products, cost savings, or competitive risks.
