SDT Signs Agreement with QAI to Build Commercial Quantum-Classical Hybrid Systems

Quantum standard technology specialist SDT (CEO Jiwon Yoon) announced on the 30th that it signed a contract with quantum AI specialist QAI (CEO Seman Lim) to 'build a hybrid quantum computing system' and will supply the first commercial quantum-classical hybrid system in Korea.

QAI will integrate and operate NVIDIA DGX-based ultra-high-performance GPU infrastructure and quantum computing at the data center level, and plans to launch commercial services in the first quarter of 2026 based on its Gangnam data center in Seoul.

This system is designed with a hybrid architecture that combines quantum processing units (QPUs) with classical computing resources (CPUs and GPUs), supporting solutions to chemistry, AI, and optimization problems that are difficult for existing supercomputers to handle. SDT provides a full-stack solution encompassing hardware and operating environment, supplying key quantum resources such as the 20-qubit superconducting quantum computer Kreo, the NVIDIA DGX B200 GPU server, and the immersion cooling system "Aqua Rack."

The quantum-classical hybrid system at the QAI data center, being built in Cheongdam-dong, Gangnam, Seoul, will serve as a pilot model to expand the quantum computing base and ecosystem. The hybrid cloud service "QuREKA" will officially launch in January 2026. QuREKA optimally allocates complex tasks to quantum and classical resources and allows users to access quantum computers and simulators via the cloud.

“By building a commercial quantum-classical hybrid infrastructure in downtown Seoul, we have created an environment that companies can immediately utilize,” said Lim Se-man, CEO of QAI. “Starting in 2026, we plan to expand industrial demand-based use cases and continue to expand urban hybrid data centers.”

“This contract is a significant milestone for domestic quantum computing, taking its first steps beyond the research stage and into the industrial field,” said Yoon Ji-won, CEO of SDT. “We will support the hybrid system in the heart of Seoul to become a key hub for accelerating the utilization of quantum technology in the industry.”
