On torsion-free modules and semi-hereditary rings
arXiv preprint (Accepted: To appear in Tokyo J. Math.) , December 2024. Link: arXiv:2412.16618
We prove several results concerning the structure theory of the class of semi-hereditary rings, focusing on the relationship between semi-hereditary rings and the flatness of torsion-free modules.

Some topics on non Noetherian commutative rings Permalink
Published:
Abstract
Homological methods are well studied in commutative ring theory. These methods have been used to study the properties of ideals in rings whose ideals are not necessarily finitely generated. In this talk, we introduce the generalization of the theorems of Noetherian rings by homological methods and topics of classes of some rings.
Introduction to Quantum Information Technology Permalink
Published:
Abstract
Quantum information technology is not only of theoretical and research importance, but is also being actively used in industry. In this talk, we will give an overview of industrial trends not only in Japan but also in the world, and introduce the potential applications of quantum sensors, including several case studies.

Bridging Industry and Academic research: Advancing Digital, Green, and Quantum Education Permalink
Published:
Abstract
This talk surveys SKILLUP NeXt’s work in AI/DX talent development and GX (Green Transformation), then outlines our plan to scale up quantum-technology education. By offering joint lectures and hands-on workshops with OIST and Q-STAR, and by leveraging cloud-based quantum computing platforms, we pursue both expert training and broad public outreach.
This work was performed for Council for Science, Technology and Innovation (CSTI), Cross-ministerial Strategic Innovation Promotion Program (SIP), “Promoting the application of advanced quantum technology platforms to social issues”(Funding agency : QST).

Q-STAR における量子人材育成に関する取り組み (Q-STAR’s efforts in fostering quantum human resources) Permalink
Published:
Abstract
Q-STAR is an industry-academia-government consortium launched in 2021 to create new industries based on quantum technologies and to enhance Japan’s international competitiveness. This presentation outlines a human-resource development strategy designed to enable ten million people in Japan to make practical use of quantum technologies and to generate economic value on the order of 50 trillion yen by 2030. We describe multifaceted initiatives to cultivate quantum-skilled personnel—including the formulation of a common “Quantum Skill Standard,” the cross-sector SIP Education Program (featuring an introductory course and an OIST-based research-training track, a Global Leader Program linked to TQC 2024, and outreach events for the general public). Together, these efforts will establish an end-to-end pipeline that supports everything from R&D sites and supply chains to start-up creation, thereby accelerating the social implementation of quantum technologies.
