Background
The convergence of quantum computing (QC) and high-performance computing (HPC) is increasingly recognized as a crucial pathway to tackling grand scientific challenges. Hybrid quantum-classical architectures are designed to leverage the strengths of both paradigms: classical HPC for demanding tasks like data preparation and post-processing, and quantum processors for specific, intractable computational kernels. Japan, a global leader in supercomputing with its flagship Fugaku system, is actively investing in this synergistic hybrid approach. The RIKEN Center for Computational Science (R-CCS) has now taken a significant step forward by launching its new “ROQUO” supercomputer, engineered specifically for profound quantum-HPC integration.
Key Findings
- Official Commissioning of “ROQUO”: The RIKEN Center for Computational Science (R-CCS) has officially commissioned “ROQUO,” a new JHPC-quantum GPU supercomputer. This system is purpose-built to accelerate the synergistic integration of quantum computing and high-performance computing.
- Strategic National Investment: ROQUO’s deployment is a key component of a commissioned project by the New Energy and Industrial Technology Development Organization (NEDO), underscoring Japan’s national strategic investment in this advanced computing paradigm.
- Formidable Classical Performance: ROQUO delivers formidable classical computing power, achieving 19.80 petaflops in double-precision floating-point operations. This robust HPC capability is designed to serve as a powerful backbone for sophisticated hybrid quantum-classical workflows.
- Diverse Quantum System Integration: The ROQUO platform is engineered to seamlessly integrate with R-CCS’s flagship Fugaku supercomputer and leading quantum hardware, including IBM Quantum System Two and Quantinuum’s trapped-ion quantum computer. This multi-modality integration offers researchers access to a diverse array of state-of-the-art quantum resources.
Significance & Outlook
The commissioning of “ROQUO” represents a major advancement for Japan’s quantum and HPC capabilities. By establishing this powerful hybrid quantum-HPC platform, RIKEN R-CCS is poised to significantly enhance quantum computing simulations and accelerate the development of novel quantum algorithms. This integrated approach empowers researchers to explore complex problems that are currently beyond the reach of either classical or quantum computers alone, thereby pushing the boundaries of scientific discovery. Furthermore, by linking Fugaku with leading quantum hardware from industry giants like IBM and Quantinuum, ROQUO firmly positions Japan at the forefront of global quantum innovation. This strengthens the nation’s competitive edge in the rapidly evolving landscape of advanced computing and holds the potential to catalyze groundbreaking discoveries across diverse fields, from materials science and drug discovery to fundamental physics.
