Quantum Integrated Devices

Johannes Fink is an experimental physicist studying quantum effects in electrical, mechanical and optical chip-based devices. His main objective is to advance and integrate quantum technology for computation, communication and sensing.

Our research is positioned at the intersection of quantum optics and mesoscopic condensed matter physics. In our lab we focus on developing novel types of superconducting and photonic devices using advanced MEMS fabrication technologies. One of our main goals is to develop an on-chip integrated microwave-optic link to enable quantum communication between superconducting microwave qubits via telecom wavelength fiber optics.
