Hiroki Takahashi leaves the group

After eight years, Hiroki left the group and is now working in the group of  Prof. Y. Nakamura at the University of Tokyo. We wish him all the best for his future and thank him for his heroic efforts to achieve strong ion-cavity coupling for the first time.

New publication in the Journal of Modern Optics

Precise positioning of an ion in an integrated Paul trap-cavity system using radiofrequency signals

The fibre cavity team has published their novel scheme to localise a single trapped ion in an optical fibre cavity. The Journal of Modern Optics publication describes the translation of the rf trapping potential by adding external rf potentials. This technique is crucial to translate ions into the optimal position without causing the ions to oscillate in the trapping rf field.  Read full article


Quantum Technology Showcase Event 2017

The group presented two exhibits at the quantum technology showcase event in London. The showcase event was an exhibition where the Quantum Technology Hubs presented their latest developments to industry representatives and politicians.

The group presented a working fibre cavity system to have a life demonstration of the working principle of cavity based ion-photon interfaces. Ezra , Matthias and Costas explained the basics of fibre cavities and their applications in quantum computing, networking and other applications to many interested visitors.

Callan, Nathan and Matthias presented our portable atomic clock demonstrator. The demonstrator contained the real laser system and control electronics. A mock ion trap and vacuum system demonstrated the size and functionality of these sub-systems.

ITCM Group has won an Innovate UK grant

Together with their industry partner MSquared Ltd the ITCM group has won an  innovate UK grant. The Innovate UK grant is to develop a rugged, all fibre laser system and control electronics for applications in portable quantum technologies. The project is for a duration of 12 months and strengthens the ITCM group’s work to build a high accuracy optical atomic clock
