A deep analogy between topological materials and superconducting devices was recently theoretically established [1], in particular between a 3-dimensional topological solid and a 4-terminal superconducting junction. We propose to explore this analogy by designing and fabricating multiterminal superconducting junctions and by probing their quantized energy spectrum using circuit-QED techniques.

We are looking for a post-doc with a strong background in Quantum mechanics and familiar with microwave techniques and superconductivity, and willing to participate in team work. The candidate should have defended his/her thesis less than 3 years before starting the post-doc.

Please send CV with publications list to hugues.pothier@cea.fr.
