Precise positioning of an ion in an integrated Paul trap-cavity system using radiofrequency signals
Ezra Kassa, Hiroki Takahashi, Costas Christoforou +1
We report a novel miniature Paul ion trap design with an integrated optical fibre cavity which can serve as a building block for a fibre-linked quantum network. In such cavity quan…
Long-distance single photon transmission from a trapped ion via quantum frequency conversion
Thomas Walker, Koichiro Miyanishi, Rikizo Ikuta +7
Trapped atomic ions are ideal single photon emitters with long lived internal states which can be entangled with emitted photons. Coupling the ion to an optical cavity enables effi…
Cavity-induced anti-correlated photon emission rates of a single ion
Hiroki Takahashi, Ezra Kassa, Costas Christoforou +1
We report on the alteration of photon emission properties of a single trapped ion coupled to a high finesse optical fiber cavity. We show that the vacuum field of the cavity can si…
Fiber cavities with integrated mode matching optics
Gurpreet Kaur Gulati, Hiroki Takahashi, Nina Podoliak +2
In fiber based Fabry-Pérot Cavities (FFPCs), limited spatial mode matching between the cavity mode and input/output modes has been the main hindrance for many applications. We have…
Mølmer-Sørensen entangling gate for cavity QED systems
Hiroki Takahashi, Pedro Nevado Serrano, Matthias Keller
The Mølmer-Sørensen gate is a state-of-the-art entangling gate in the ion trap quantum computing where the gate fidelity can exceed 99\%. Here we propose an analogous implementatio…
