A theoretical group and an experimental group closely collaborate to develop a new research platform on artificial superatom. Specifically, we carry our the following three research subjects. (1) We establish the trajectory-based understanding on cooling and thermalization of nanoparticles. (2) We develop a method of optically identifying atomic ions near a nanoparticle. (3) We create a superatom in which an atomic ion is bound by a charged nanoparticle.

This study aims to explore physical properties under extreme conditions by precise local magnetic field measurement using a quantum spin microscope with quantum sensors. Using color centers such as diamond nitrogen-vacancy centers as quantum sensors, we will establish the material basis and protocols for quantum sensing, which will be applied to exploring physical properties under extreme conditions. We will tackle issues such as the quantitative observation of ultrathin mesoscopic magnets and the visualization of superconductivity under high pressure. Our challenges will open up the future of quantum spin microscopy as a usable quantum technology.

Using optical tweezer arrays and optical lattices, which have recently attracted attention as a new experimental platform for ultracold neutral atoms, we develop ultra-precise quantum measurement techniques. In particular, we develop unique approaches by making the most of the novel properties of the ytterbium atoms. We apply them for the search for new physics beyond the Standard Model of particle physics such as the test of fundamental symmetry and dark-matter search, as well as for the development of a new scheme of quantum computing.

Toward the realization of a large-scale distributed quantum computing, this project aims for an unprecedented and co-creative multi-layer design throughout hardware, architecture, and software. A platform of distributed quantum computers will be established by constructing a framework to exploit the potential performance of distributed quantum computation while tackling theory and experiment simultaneously.

In this research, we utilize a quantum sensor based on NV centers in diamond. We combine quantum and classical technologies such as sophisticated control of quantum states, high-sensitivity quantum sensing measurements, signal intensity amplification by highly polarized nuclear spin, and production of high-quality diamonds. We will develop a quantum sensing microscope that exceeds the sensitivity and spatial resolution of reported ones using NV centers. Furthermore, we aim to realize the measurement of dynamic interaction networks of biopolymers, such as proteins within cells.

Magnetic resonance imaging (MRI) have the intrinsic problem of poor sensitivity due to low nuclear spin polarization. This research aims to develop a new quantum medical diagnostic technology by creating spin hyperpolarized materials that dramatically improve the sensitivity of MRI. We will also develop unique molecular quantum sensors to enable quantum sensing of diverse chemical parameters.

We will develop a trapped-ion type quantum computer by taking advantage of multiple electronic states (qudit) and vibrational modes (boson) characteristic of a trapped atomic-ion system. By performing quantum gate operation and error mitigation based on quantum algorithms for the qudit and bosonic systems, we will explore frontiers in quantum computing by a trapped-ion quantum computer. We will further develop a molecular simulator to investigate non-adiabatic transitions in molecules and coupled oscillators using the qudit-boson hybrid system.
