[Program / Abstract]
2021.4.23 Mr. Villela, Welcome to Ohmori lab.!
2021.3.26-28 Dr. Takafumi Tomita was a lecturer at the “Quantum Information Spring School 2021” teaching about “Rydberg atom quantum simulator and computer”.
2021.3.26 Mr.Mizoguchi, Congratulations on receiving your doctor’s degree!
2021. 3.26 Prof. Ohmori was invited to give a talk about “Ultrafast and ultracold quantum simulator with attosecond precision” at EU FET Project COPAC Symposium “Parallel Computing Quantum Devices” (23-25 March 2021, Online)
2021.3.20 Prof. Ohmori was invited to give a talk at the Symposium “Quantum Computing: Status and Outlook” at the 68th JSAP (Japan Society of Applied Physics) Spring Meeting 2021 (16-19 March 2021, Online).
2021.2.19 Prof. Ohmori has been invited to give a talk about “Ultrafast and ultracold quantum simulator with attosecond precision” at the 15th Femtochemistry conference (FEMTO15 ) (25-30 July 2021, Berlin, Germany)(Postponed to 2023 due to Covid-19 pandemic).
2021. 1.7  (Update from 3G) Ever more atoms! After upgrading the optical setup last year, this time we turned to the trapping laser wavelength to make more traps. For a given laser intensity, the atoms experience a stronger confinement when the laser is closer to the atomic resonance. By going three times closer to the 5S-5P resonance, we could increase the number of traps from 225 to 800 (the world’s largest level). While it comes with drawbacks (more scattering, larger vector light shifts), we have been able to deal with them so far. Next step: a few thousand atoms?
2021. 1.4 Prof. Ohmori was invited to give a talk about “Ultrafast and ultracold quantum simulator with attosecond precision” at DAMOP 2021 (52nd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics). (31 May-4 June 2021, Online)
2021.1.4 Happy new year! Dr. Sylvain de Léséleuc gave an invited lecture on “Many-body physics with Rydberg atoms” at a workshop organized by Dept. Applied Physics, The University of Tokyo (‘New Developments of Applied Physics’).
