Circuit QED with hybrid electronic states

Circuit QED with hybrid electronic states

Objective

We propose to develop a new scheme for detecting and manipulating exotic states formed by combinations of conductors with different dimensionalities and/or electronic orders. For that purpose, we will use tools of cavity quantum electrodynamics to study in a very controlled way the interaction of light and this exotic matter.
Our experiments will be implemented with nanowires connected to normal, ferromagnetic or superconducting electrodes embedded in high finesse on-chip superconducting photonic cavities. The experimental technique proposed here will inaugurate a novel method for investigating the spectroscopy and the dynamics of tailored nano-systems.
During the project, we will focus on three key experiments. We will demonstrate the strong coupling between a single spin and cavity photons, bringing spin quantum bits a step closer to scalability. We will probe coherence in Cooper pair splitters using lasing and sub-radiance. Finally, we will probe the non-local nature of Majorana bound states predicted to appear at the edges of topological superconductors via their interaction with cavity photons.
