South Korea’s SDT Inc. has opened its Quantum-AI Hybrid Data Center in Seoul's Gangnam district — billed as the country’s first commercial quantum computing facility.
The company has also deployed a 20-qubit superconducting quantum computer dubbed Kreo at the facility, integrating the system with Nvidia DGX B200 hardware using the chip designer’s NVQLink platform.
The Kreo and Nvidia B200 systems are integrated in an immersion-cooled environment using SDT’s AquaRack system. Using single-phase immersion fluid, the company claims AquaRack can cut cooling power loads by up to 90 percent while delivering up to 45kW per 21U rack.
The deployment marks the first time that Korea has seen a commercial hybrid quantum‑classical system be deployed in an industrial data center environment instead of a national lab, the company said in a LinkedIn post.
SDT went on to add that the Quantum-AI Hybrid Data Center is the culmination of the company’s proprietary full-stack QDM (Quantum Design & Manufacturing) capabilities, which encompasses hardware design, fabrication, system integration, and operating software.
By combining its Qubit Controller Unit (QCU) – which provides high‑fidelity multi‑qubit control and readout for Kreo – with Nvidia hardware, STD said it has created “low-latency workflows for chemistry simulation, portfolio optimization, and logistics applications.”
This architecture allows the Nvidia DGX B200 systems to handle numerically intensive workloads, such as data encoding, variational optimization, control loops, and result post-processing, while the QPU (quantum processing unit) dispatches latency-sensitive quantum kernels and problem primitives.
“Until now, quantum computing has largely remained within the realm of academic research in Korea,” said Jiwon Yune, CEO of SDT. “Starting today, we are redefining quantum as a practical business tool for immediate value creation. By operating this system in Gangnam—the business heart of Korea—we are demonstrating that quantum computing is no longer a distant concept, but a tangible solution ready to engage with real industrial challenges.”
