NVIDIA has launched a groundbreaking initiative in supercomputing with the establishment of the Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT), located in Japan. At the heart of this center is ABCI-Q, now recognized as the world’s largest supercomputer fully dedicated to quantum computing research.

ABCI-Q is engineered to address some of the planet’s most pressing challenges — from advancing healthcare solutions to tackling complex problems in energy and finance. By integrating quantum processors with AI-powered supercomputers, it aims to significantly accelerate progress in fields demanding massive computational capabilities.

Developed and delivered by Japan’s National Institute of Advanced Industrial Science and Technology (AIST), the ABCI-Q system runs on 2,020 NVIDIA H100 GPUs, all interconnected using NVIDIA’s ultra-fast Quantum-2 InfiniBand networking platform. This infrastructure allows researchers to process and analyze vast amounts of data with exceptional speed and efficiency. Figure 1 shows ABCI-Q supercomputer.

At the core of ABCI-Q is CUDA-Q™, NVIDIA’s open-source hybrid computing platform. CUDA-Q plays a crucial role in orchestrating the complex interplay between hardware and software required to support large-scale quantum applications.

“Seamlessly coupling quantum hardware with AI supercomputing will accelerate realizing the promise of quantum computing for all,” said Tim Costa, Senior Director of Computer-Aided Engineering, Quantum, and CUDA-X™ at NVIDIA. “Our collaboration with AIST will drive advancements in key areas such as quantum error correction and application development — both vital for building practical, accelerated quantum supercomputers.”

Hybrid Architecture Integrates Multiple Quantum Platforms

ABCI-Q stands out for its hybrid architecture, which brings together various quantum technologies from multiple leading companies. This includes a superconducting qubit processor developed by Fujitsu, a neutral atom processor from QuEra, and a photonic quantum processor from OptQC. This diversified system supports a wide range of quantum workloads, enabling researchers to evaluate and compare different quantum computing models on a single unified platform.

This multi-modal approach serves as a strategic “stepping stone,” enabling scientists to explore the near-term capabilities of quantum computing and accelerate the journey toward real-world applications.

“ABCI-Q will give researchers in Japan the tools to investigate fundamental quantum computing challenges and speed the development of practical use cases,” said Masahiro Horibe, Deputy Director of G-QuAT and AIST.

Expanding Global Efforts in Quantum-AI Research

NVIDIA’s efforts extend far beyond Japan. In Taiwan, the National Center for High-Performance Computing (NCHC) recently announced a new supercomputer dedicated to quantum research. Built by ASUS, the system will include over 1,700 NVIDIA GPUs across HGX H200 systems, along with next-gen GB200 NVL72 and HGX B300 systems based on the Blackwell Ultra platform.

Scheduled to go live later this year, the system will use NVIDIA Quantum InfiniBand networking and support more than 20 companies participating in Taiwan’s National Quantum Team. Like ABCI-Q, it will also leverage NVIDIA CUDA-Q for research in areas such as machine learning and quantum chemistry.

“AI has sparked a new industrial revolution — transforming both science and industry,” said Jensen Huang, Founder and CEO of NVIDIA. “We’re proud to partner with Foxconn and Taiwan to help build a robust AI infrastructure, and support TSMC and other leaders driving innovation in the era of AI and robotics.”

Driving Global Momentum for Quantum-AI Integration

Quantum computing is rapidly emerging as a transformative tool for solving highly complex computational problems — from drug discovery and molecular simulations to optimizing logistics and financial systems.

NVIDIA is leading the charge by fusing today’s most advanced AI supercomputers with the quantum technologies of tomorrow. At the COMPUTEX tech trade show, the company showcased its global initiatives — including in Taiwan and Japan — that are helping push quantum research to the next level.

Leading academic institutions and companies such as Atlantic Quantum, University of Edinburgh, University of Oxford, Quantum Circuits Inc., QuEra Computing, and Yale University are also joining the movement. These organizations plan to utilize NVIDIA Grace Hopper Superchips provided by Supermicro, enabling them to explore the powerful synergy between AI and quantum computing.
