SDT Inc. has inaugurated Korea's first commercial quantum computing center, located in Seoul's Gangnam district. The facility integrates SDT's 20-qubit superconducting quantum computer, Kreo, directly with NVIDIA DGX B200 systems, leveraging the NVQLink platform to establish a hybrid quantum-classical computing environment1. This Quantum-AI Hybrid Data Center combines SDT's Qubit Controller Unit with NVIDIA's GPU-accelerated classical compute resources, specifically engineered to enable low-latency workflows. The aim is to accelerate solutions for computationally intensive tasks such as advanced chemistry simulations, complex portfolio optimization strategies, and intricate logistics applications. Access to these cutting-edge capabilities is provided through SDT's proprietary QuREKA cloud platform. The operationalization of such commercial hybrid quantum infrastructures signifies a tangible progression in quantum technology accessibility, fundamentally narrowing the timeline for anticipated cryptographic shifts and elevating the critical need for proactive post-quantum cryptography (PQC) planning and deployment across all sectors.
