Characterization and fabrication of superconducting multi-qubit devices

Superconducting quantum circuits form the basis of current quantum processing platforms that allow to run first algorithms. However, to make practical use of coherent quantum systems, there is considerable fundamental challenges ahead: overcoming decoherence of qubits caused by interactions with an uncontrolled environment, improving qubit control to avoid systematic errors, developing scalable multi-qubit architectures while maintaining high level of coherence, or the efficient generation of highly-entangled quantum states in quantum-classical hybrid schemes.

In this project, we plan to design and fabricate high-coherence superconducting microwave circuits (qubits and couplers) that allow for multi-qubit operations and therefore enhance the connectivity of a quantum processor. The characterization of these circuits in a cryogenic microwave measurement setup is an integral part of the project. The master project also consists of fabrication of the circuits using state-of-the-art micro- and nanofabrication techniques.
