Main Research

(1)Development of highly accurate/-precise frequency standard using optical lattice clocks.

see more detail

(2)Coherent atom control by atom-chip and/or atom IC

(3)Generation of Quantum entanglement by cooled atom

On research (1), we aim to achieve clock precision at 18-digit, and examine the constancy and time-fluctuation of physical constants based on our original idea of "Optical Lattice Clock". Research (2) and (3) aim to substitute conventional electronics with quantum electronics for creating new information processing systems, and we are carrying out research to realize quantum computer.
