What's New ?
Kick-off meeting; JST MIRAI Large Project, “Space-time information platform with a cloud of optical lattice clocks”, starting from Nov. 2018, was held at Koshiba Hall in March 28th, 2019.
PRESS: ”Operational Magic Intensity for Sr Optical Lattice Clocks” published in Physical Review Letters, Dec.2018.
Two sets of optical lattice clock system were carried and installed to Tokyo Sky Tree for gravitational potential measurement from Oct. 2nd midnight to Oct 3rd morning. NHK Ohayo Nippon, Asahi Sinbun, The Mainichi reported on it.
NHK News 7 reported on Prof. Katori and his group’s research planning of gravitational potential measurement with their optical lattice clock at Tokyo Sky Tree.
Prof. Katori was awarded "The 14th Leo Esaki Prize" for "Invention and realization of high-precision optical lattice clocks".
Homepage has renewed
Dr. Takamoto (Research Scientist, RIKEN) was awarded “The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology (MEXT), Prize for The Young Scientists’ Prize”.
(1)Development of highly accurate/-precise frequency standard using optical lattice clocks.
(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.
