RESEARCH

01

QUANTUM SIMULATION

Due to their excellent controllability, a system of ultracold atoms loaded into an optical lattice is considered as an ideal quantum simulator for strongly correlated quantum many-body systems. In our laboratory, by working with ytterbium atoms, we have studies the SU(N) Hubbard model, qunatum gas mixtures, non-equilibrium quantum dynamics, open quantum systems with controlled dissipation, and the development of quantum gas microscopy, and so on. We continue to pursue unique possibilities with this system.

02

PRECISION MEASUREMENT

We explore new physics beyond the Standard Model through precise spectroscopy of ultracold ytterbium atoms trapped in optical lattices and optical tweezers arrays, leveraging the unique properties of ytterbium atoms that are highly sensitive to new physics. Our research includes searching for new particles via precise isotope shift measurements, test of Lorentz invariance, precision measurement of CP-violating magnetic quadrupole moment, and dark matter search using Rydberg atoms.

03

QUANTUM COMPUTATION

Our goal is to build a quantum computer using ultracold ytterbium atoms. We capture and arrange atoms one by one by using optical tweezer array technology, and precisely manipulate their quantum states to achieve high-fidelity quantum gates. A system of ultracold ytterbium atoms offers long coherence times and high controllability, making it ideal for realizing fault-tolerant quantum computers.
