With atoms coupled to optical cavities it is possible to build up quantum interfaces between stationary and flying qubits. A quantum network based on these interfaces offers a compelling solution to the challenge of scalability in quantum computing. By using fiber-based cavities, we expect to reach the strong coupling regime of cavity quantum electrodynamics with single ions.
To that end, we further developed the laser ablation of fiber facets and produced them in a collaboration with the group of Jakob Reichel. The fiber facets are then coated to produce high-finesse fiber mirrors. Specifically, we plan to produce cavities of about 8 µm mode waist and 500 µm in length for use in our integrated ion-trap cavity setup. In parallel, we are currently building a new miniaturized calcium ion trap in the “Innsbruck” linear design.
