Insights

NVIDIA's integration of GPUs with quantum systems positions it as a leader in the emerging quantum-AI hybrid computing market.

NVIDIA's announcement about powering the ABCI-Q supercomputer represents a significant strategic positioning in the quantum computing landscape. Rather than competing directly with quantum hardware makers, NVIDIA is creating an essential bridge between classical and quantum computing systems—a market strategy that leverages their existing strengths while expanding their relevance into quantum computing.

The architecture combining 2,020 H100 GPUs with the NVIDIA Quantum-2 InfiniBand networking platform creates what's essentially a quantum simulator and interface system of unprecedented scale. This approach is particularly clever because it addresses quantum computing's current limitations: today's quantum processors have too few qubits and too much noise to solve meaningful problems alone. By pairing them with GPUs, NVIDIA creates hybrid systems that are practically useful now, not just in some distant future.

What's technically innovative here is the integration with multiple qubit modalities (superconducting, neutral atom, and photonic), allowing researchers to explore different quantum architectures simultaneously. This flexibility is crucial because there's still no consensus on which quantum technology will ultimately prove most scalable.

The CUDA-Q platform further strengthens NVIDIA's position by establishing their software as the orchestration layer for quantum-classical workflows. This parallels how CUDA became the standard for GPU computing, potentially giving NVIDIA significant control over the software ecosystem as quantum computing matures.

For context, quantum error correction research—specifically mentioned in the release—is the most critical challenge facing quantum computing today. By accelerating this research, NVIDIA's system could help reduce the timeline to fault-tolerant quantum computers from decades to years.

AIST’s ABCI-Q Supercomputer Equips Researchers to Realize the Potential of Quantum Computing

TAIPEI, Taiwan, May 19, 2025 (GLOBE NEWSWIRE) -- COMPUTEX — NVIDIA today announced the opening of the Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT), which hosts ABCI-Q — the world’s largest research supercomputer dedicated to quantum computing.

Quantum processors promise to augment AI supercomputers in solving some of the world’s most complex challenges, spanning industries including healthcare, energy and finance. By enabling quantum-GPU computing at an unprecedented scale, ABCI-Q marks a profound leap toward realizing practical, accelerated quantum systems.

Delivered by Japan’s National Institute of Advanced Industrial Science and Technology (AIST), the ABCI-Q supercomputer features 2,020 NVIDIA H100 GPUs interconnected by the NVIDIA Quantum-2 InfiniBand networking platform.

The system is integrated with NVIDIA CUDA-Q™, an open-source hybrid computing platform for orchestrating the hardware and software needed to run useful, massive-scale quantum computing 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. “NVIDIA’s collaboration with AIST will catalyze progress in areas like quantum error correction and applications development — crucial for building useful, accelerated quantum supercomputers.”

ABCI-Q’s AI supercomputing is integrated with a superconducting qubit processor by Fujitsu, a neutral atom quantum processor by QuEra and a photonic processor by OptQC — enabling hybrid quantum-GPU workloads across multiple qubit modalities.

“ABCI-Q will enable researchers in Japan to explore the core challenges quantum computing technologies face and speed the path to practical use cases,” said Masahiro Horibe, deputy director of G-QuAT and AIST. “The NVIDIA accelerated computing platform in ABCI-Q will empower scientists to experiment with the stepping-stone systems needed to advance quantum computing.”
