Ion Trap Quantum Metrology Lab
Machine-translated · View original
A lab that develops on-chip ion traps to manipulate atoms one by one.
AboutAbout the lab
On-chip ion traps that manipulate atoms one by one.
The Ion Trap Quantum Metrology Lab researches and develops on-chip ion traps that combine atomic physics with microfabrication technology.
Building on ion trap and laser cooling technologies that individually manipulate atoms at the level of single atoms, the lab advances its research in collaboration with research institutions in Japan and abroad that have microfabrication expertise.
The lab pursues a wide range of research activities, including participation in a national project to pioneer new quantum information and quantum metrology technologies, and the establishment of an international joint lab between Osaka University and the Physikalisch-Technische Bundesanstalt (PTB) of Germany.
On the lab's website, it is introduced under the name “Utako Tanaka Group.”
Key terms
- On-chip ion trap
- A device that traps atomic ions, fabricated on a substrate. It is made by combining atomic physics with microfabrication technology.
- Nanofriction model
- A model for exploring the origin and control of friction at the atomic level.
- Superradiant laser
- A laser that aims to exceed the limits of current atomic clocks by using the collective spontaneous emission of atomic ions.

ResearchResearch themes
The lab develops on-chip ion traps that combine atomic physics with microfabrication technology. The arrangement of laser-cooled atomic ions can be set and the ions manipulated individually, and the lab states that this can be applied to quantum metrology, quantum computing, and quantum simulation.
*Illustrative imageIon–light coupled systems toward superradiant lasers
The lab aims for a superradiant laser that exploits the collective spontaneous emission of atomic ions to surpass the limits of current atomic clocks. To this end, it builds systems in which multiple ions are coupled to light.
*Illustrative imageImplementing the nanofriction model
The lab uses the two-row ion arrangement that only this lab has achieved for a nanofriction model that explores the origin and control of friction at the atomic level. The lab states that reducing friction in micromachines and similar devices could lead to energy savings.
*Illustrative imageIntegrated quantum interface
Because on-chip ion traps are fabricated on a substrate, they are highly compatible with photonic integrated circuits. The lab integrates the coupling between atomic ions and light, which is essential for scaling up quantum information processing, and makes it work as a quantum device.
