The First RIKEN Quantum International Workshop on Frontiers of Quantum Computing Applications and Quantum-HPC Integration
Overview
This two-day workshop will bring together leading experts from academia, industry, and national laboratories to explore the rapidly evolving frontiers of quantum computing applications and their integration with high-performance computing (HPC) platforms.
Hosted by RIKEN Quantum, the event will provide a forum for discussing recent advances, practical challenges, and future directions toward achieving utility-scale quantum computations and robust quantum–HPC hybrid workflows.
Scope and Objectives
The workshop aims to foster interdisciplinary discussion and collaboration at the intersection of quantum information science, physics, quantum chemistry, life science, and scientific computing. Key areas of focus include:
- Applications of quantum algorithms to quantum many-body problems in quantum chemistry, condensed matter physics, atomic physics, and high-energy physics
- Hybrid quantum–classical computational approaches that tightly integrate quantum processors with HPC resources
- Emerging applications of quantum computing in solving differential equations, computational fluid dynamics (CFD), and computer-aided engineering (CAE)
- Early fault-tolerant quantum computing (early FTQC) and its applications
- Large-scale classical simulations of quantum many-body systems
- Pathways toward utility-scale applications and demonstrations of quantum advantage
By bringing together researchers across diverse domains, the workshop aims to accelerate the development of computational strategies that synergistically combine quantum and classical resources and to chart a realistic path toward practical quantum computing applications.
Discussion Themes
- How can quantum–HPC integration accelerate progress toward real-world scientific and engineering applications?
- What are the roles of large-scale classical simulations in benchmarking and guiding quantum algorithm development?
- What are the near-term possibilities with early fault-tolerant quantum devices?
- What strategies and architectures can enable scalable, reproducible quantum–HPC workflows?
- How can we define and achieve quantum advantage in meaningful application domains?
