Ministry of Internal Affairs and Communications National Project (MIC) “Research and development of key technologies for realizing the quantum internet”
Term: FY2023-2027
Project Name: NEDO Leading Research Program / Frontier Development Program
Frontier Area: Quantum Sensing (Development of Core Technologies for the Industrialization of Quantum Sensing, Optical Lattice Clocks, Atomic Clocks, Diamond NV Centers, etc.)
Selected Project: Development of Diamond Photonic Crystal Quantum Sensors
Principal Investigator: Hideo Kosaka
Collaborating Institutions: Toyohashi University of Technology; The University of Tokyo (Joint Research Institution); National Institute for Materials Science (Joint Research Institution); National Institutes for Quantum Science and Technology (Joint Research Institution)
The Frontier Development Program is a national initiative that promotes research and commercialization in emerging fields with the potential to create new industries beyond 2040.
Our project aims to develop diamond photonic crystal quantum sensors capable of highly sensitive, high-resolution measurements of electrical current, magnetic fields, temperature, and other physical quantities, as well as high-throughput quantum imaging.
By advancing Diamond-on-Insulator (DOI) technology for the stable and cost-effective production of quantum-grade diamond, together with photonic integration, chiplet technologies, and precision measurement techniques, the research seeks to establish key technologies for future industrial applications.
In addition to applications such as non-destructive semiconductor inspection, the project also aims to establish a quantum technology platform that can contribute to future advances in quantum computing and quantum communication, building on QIC’s expertise in quantum repeater research.
Japanese Principal Investigator: Dr. Takeshi Oshima (Director of the Takasaki Institute for Advanced Quantum Science, National Institutes for Quantum Science and Technology (QST))
German Principal Investigator: Professor Fedor Jelezko (Professor at the Institute of Quantum Optics, Ulm University, Germany)
Title: Diamond spin qubits for quantum applications (DIAMONDQTECH)
Professor Kosaka’s（Co-PI） research theme: Quantum Communication
Term: FY2025-2029
The ASPIRE Program (Adopting Sustainable Partnerships for Innovative Research Ecosystem) aims to strengthen and enhance Japan’s scientific and technological capabilities. It fosters international collaboration in strategically important scientific fields by connecting top researchers from Japan to researchers in advanced STI countries and regions. The program seeks to accelerate the international circulation of talent within Japan’s research community.
In the Japan-Germany joint research field of quantum technologies the project “Diamond spin qubits for quantum applications (DIAMONDQTECH)” has been selected. Professor Kosaka will participate as a Co-PI (Principal Co-Investigator) for the research theme “Quantum Communication.”
