The international joint research lab TRiAC (TRapped-Ion integrated Atomic-photonic
Circuit) builds on a long scientific collaboration between QUEST at PTB,
Germany, and Osaka University, Japan on trapped ion research. Created by
the groups of Tanja Mehlstäubler, Christian Ospelkaus, Kazuhiro Hayasaka,
and Utako Tanaka.
TRiAC is aimed at exploring many-body quantum systems using laser-cooled
ions. It will develop microfabricated ion-trap electrodes for novel ion
configurations, perform quantum simulation of many-body quantum systems
and investigate generation of superradiance with ions. This study is significant
not only for fundamental Physics but also for a large-scale quantum information
processing and novel atomic clocks.
TRiAC is stimulated by the collaborative grant JSPS-DAAD and supported
by Osaka University's International Joint Research Promotion Program. It
promotes exchange of researchers and students.
Mr. Onur Asik has joined Tanaka Group October 2023
Mr. Onur Asik has joined Tanaka Group as an international student of the
FrontierLab @ OsakaU program. We held a welcome party for him on Oct. 13th.
Prof. Tanja Mehlstäubler of LUH and PTB visited us Oct. 26-31, 2022
Prof. Tanja Mehlstäubler of LUH and PTB visited us and provided two seminars
entitled "Scalable and integrated chip ion traps” and "A novel
mixed species In+/Yb+ ion optical clock" These seminars were
sponsored by C-Pair of Graduate School of Engineering Science, and cosponsored
by QIQB. Since the seminars were hybrid meetings, there were participants
of not only OU but also NICT, The University of Tokyo and OIST.
TRiAC workshop was held on March 26, 2021
TRiAC online workshop was held on March 26, 2021. 11 speakers from both
Japan and Germany provided talks and totally 52 researchers and students
attended.

Development of microfabricated ion trap for a nanofriction model emulator
Ion trap electrode fabricated at PTB, implimented at Osaka University.
We develop a microfabricated ion trap that is applicable as a nanofriction
model emulator and studies of many-body dynamics of interacting systems.
The trap is designed by the group of Osaka University, which enables both
single-well and double-well potentials in the radial direction [1]. Investigation
of a nanofriction model using two-dimensional ion configuration [2] is
one of the applications of such trap. An improved fabrication process performed
at PTB allows down-sizing the trap, which can be used as an nanofriction
model emulator [3].
