IonQ Expands South Korean Footprint with SDT Quantum Computing Deal

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

SEOUL, South Korea and COLLEGE PARK, Md., Sept. 21, 2026 — IonQ 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.
