Offer Description

Background of the recruitment and description of the project Background of the recruitment and description of the project Research Field The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international hub for computational science that promotes “science of computing, by computing, and for computing.” R-CSS positions the technology in which RIKEN has strengths (R-CCS technology) and the software developed by RIKEN that contributes to science, technology, industry, and society (R-CCS software) as its “core competence in computational science driving science as a whole.” R-CCS aims to develop these technologies, disseminate them domestically and internationally, and produce results. In addition, R-CCS is utilizing its expertise to operate the supercomputer “Fugaku” which was developed as a national project in accordance with Japanese laws and regulations.

One of our main focuses is to develop state-of-the-art numerical methods for simulating ground states as well as quantum dynamics of strongly correlated quantum systems. In addition, we are exploring new computing paradigms as a grand challenge for information science. In particular, we are engaged in research and development of quantum computing for simulating quantum many-body systems, and of quantum computational simulations using classical computers.

details of the business RIKEN is Japan's largest and most comprehensive research organization for basic and applied science.

Work content and job description In accordance with the research project of NEDO “Research and Development of Quantum-Supercomputer Hybrid Computing Platform for Exploring Computable Regions” (PI: Mitsuhisa Sato (RIKEN), Research Period: November 2023 – October 2028), the following item(s) will be carried out in collaboration with other project members: (i) research and development of quantum computing simulations using methods such as tensor network for the quantum-HPC hybrid computing platform, (ii) research and development of the optimization of quantum-HPC hybrid computing programs such as error suppression and mitigation methods, as well as quantum circuit optimization techniques, (iii) research and development of quantum-HPC hybrid applications mainly focusing quantum many-body systems, and verification of the effectiveness of the quantum-HPC hybrid computing platform developed in this project.

The job description may be changed during the contract period or upon contract renewal to the extent described above.
