Ion traps as nodes in a fiber-cavity quantum network — •Robert Maiwald1, Tim Ballance1,2, Martin Link1, Hendrik M. Meyer1, and Michael Köhl1 — 1Physics Institute, University of Bonn, Germany — 2Cavendish Laboratory, University of Cambridge, UK
Linking quantum systems across larger topologies requires strong light-matter interaction as well as excellent control over the quantum systems themselves, enabling applications such as entanglement distribution, quantum simulation, and distributed quantum computing. We approach this research area by combining fiber-based cavities and ion traps, with the goal to capitalize on both the benefits of high-finesse cavities and the established quantum control of trapped atomic ions.
The talk will highlight our recent progress in realizing individual nodes of a quantum network based on trapping Yb-ions in specialized Paul-type ion traps with integrated fiber cavities. We will present ways to incorporate fiber-cavities in more versatile traps and discuss scalability of our system.
