Korea’s first commercial open superconducting quantum computer and hybrid computing data center

Operating on Dosan-daero, Gangnam-gu, Seoul, KREO SC-20 is Korea's first commercial quantum computer. Built with SDT's Full-stack QDM (Quantum Design & Manufacturing) technology, KREO SC-20 is a 20-qubit superconducting quantum computer. It is an open system designed to link organically with classical computing resources such as GPUs and CPUs within a single architecture.


The system features a 20-qubit superconducting Quantum Processing Unit (QPU) from partner Anyon Technologies, SDT's qubit control equipment (QCU), and the CryoRack cryogenic dilution refrigerator as core components. It integrates with NVIDIA DGX B200 GPU systems via NVLink to provide a quantum-AI hybrid computing environment.

Operating live in the heart of Seoul’s Gangnam business district, KREO SC-20 is South Korea’s first commercial 20-qubit superconducting quantum computer. Officially launched in February 2026 with the support of leaders from both public and private sectors including NVIDIA, Microsoft Korea, and LG Electronics, this facility brings quantum computing out of the lab and straight into the enterprise world as a tangible, industrial-grade solution.


Built on SDT’s proprietary Full-Stack QDM (Quantum Design & Manufacturing) capabilities, KREO establishes a tightly integrated hybrid workflow. By directly coupling a state-of-the-art superconducting QPU from our partner Anyon Technologies with NVIDIA DGX B200 GPU systems, the architecture leverages NVIDIA NVQLink platform to enable real-time, high-fidelity feedback. This sets a new benchmark for computational performance, specifically engineered to accelerate advanced AI workloads and deliver a practical path toward true quantum advantage.


Enterprises can seamlessly access this immense computing power through QuREKA, our all-in-one hybrid quantum cloud platform. By unifying GPU and QPU resources into an intuitive, ready-to-use development environment, QuREKA provides an immediate commercial on-ramp for reliable, enterprise-grade quantum-AI hybrid computing. It delivers a secure, fully managed infrastructure for designing, testing, and scaling hybrid workloads with confidence. Pioneering the next era of computation, the KREO series is breaking through traditional bottlenecks, driving transformative progress for industries facing complex computational challenges.

KREO NA is a quantum computer system based on neutral atom and ion trap qubits, offering long coherence times and high qubit connectivity. It is designed to link organically with classical computing resources like GPUs within a single architecture.


The system operates on QubeCore, a quantum OS developed in-house by SDT, and precisely controls qubits with laser pulses via the Kasli FPGA controller based on the open-source ARTIQ framework. This provides an integrated solution optimized for academic and research neutral atom and ion trap system environments, allowing both modalities to be utilized together on the same operating system as KREO SC.
