IonQ said in a post on X that it will supply SDT, Inc. with a Superion 256 quantum computer and silicon-vacancy (SiV) quantum memory in a multi-year collaboration. The partnership is set to bring the first Superion 256 system and first SiV quantum memory module to South Korea, according to the company announcement.
The Superion 256 system is planned for an SDT customer site in South Korea. IonQ and SDT also plan to work on a hybrid quantum-classical data center there.
The arrangement extends their prior cloud-based software integration into hardware production, assembly and regional resale. SDT plans to build a quantum manufacturing and system-integration facility in Gumi, South Korea, for IonQ's SiV memory packaging and manufacturing, as well as quantum-system assembly, integration and commissioning.
IonQ CEO Niccolo de Masi said the company is expanding its commercial footprint in South Korea while continuing quantum cancer and biomedical research. SDT intends to develop hybrid quantum-classical infrastructure for medical and biomedical research with IonQ through a separate in-country cancer center initiative.
SDT CEO Jiwon Yune said the Gumi facility is intended to serve as an operational hub for IonQ's global supply chain and regional deployment. SDT is a South Korea-based quantum technology company that provides hardware, software and system integration, and it was named a World Economic Forum Technology Pioneer in 2026.
IonQ, headquartered in College Park, Maryland, builds trapped-ion quantum computers and related software. The company said it achieved 99.99% two-qubit gate fidelity in 2025, which it called a world record. IonQ reported $80.1 million in Q2 2026 revenue, up 287% from $20.7 million in Q2 2025, and raised its full-year 2026 revenue guidance to $280 million to $290 million.
