Greetings
National Institutes for Quantum Science and Technology (QST), as the "Foundational Quantum Technology Hub", one of Japan's Quantum Technology Innovation Hubs (QIH), carries out sophisticated manipulation of quantum states and realize advanced quantum measurements by taking advantage of quantum beam and laser (photon) technologies. Also, we perform R&D of foundational quantum technologies, and support industry through the development of quantum materials with advanced quantum functionality by trial and assay of quantum materials and quantum technologies, and furthermore tailoring their properties to the environment in which they will be used. We, the Quantum Materials and Applications Research Center (QUARC), as a core part of the QIH's "Foundational Quantum Technology Hub", are conducting a wide variety of research on quantum materials and their functionalization, from basic science to the applications of these materials such as device fabrication process. Using accurate and advanced techniques for spin and photon manipulation, as well as their entanglement, we carry out unique world-leading research. We play an important role as a R&D hub for quantum technology, promoting cooperation among government, academia and industry.

Study of Quantum Materials and Functionalization leading the world
Quantum Materials Functionalization Group
This group investigates the creation of spin defects which act as quantum sensors in wide bandgap semiconductors such as diamond and silicon carbide using ion and electron beams. We explore quantum sensing based on such spin defects to establish extremely high sensitive sensing technology for magnetic field and temperature measurements.
Quantum Sensing Application Technology Group
This group promotes applied research for social implementation of solid-state quantum sensors using spin defects formed in diamond and silicon carbide.
Spin-Photonic Quantum Materials and Applications Group
This group aims to explore spin-photonics by developing novel quantum materials which enable efficient photon-spin interconversion and optically driven spintronic devices based on two-dimensional materials and advanced magnetic materials.
Laser-Cooled Ion Group
This group promotes R&D studies on ion trap and laser cooling techniques, and on their applications to quantum information processing and ultraprecise ion implantation.
Quantum Optical and Spin State Control Group
This group focuses on the precise control and structural analysis of quantum states in semiconductor heterostructures and spin-related complex defects using advanced optical and electrical detection techniques. We are also developing new materials and verifying their spin and quantum-related functionalities in order to establish the fundamental technologies necessary for the next generation of information technology using quantum communication.
Quantum Materials Theory Group
This group promotes theoretical research and development of novel quantum materials and devices, of algorithms for (gate-type) quantum computers, and of quantum error correction technology by utilizing first-principles (non-empirical) theoretical calculations.
Rare-Earth Quantum Device Group
This group aims to develop new types of quantum devices using rare-earth ions in nitride semiconductors as quantum bits, single photon sources, and quantum entangled light sources. This project also aims to develop new quantum sensing methods using the opto-electronic and spin properties of rare-earth elements.
