Transmons play the strings: Coupled mechanical and superconducting quantum circuits for probing vibrational modes and the transfer of quantum states

Circuit nano-electro mechanics is a new field in the overlap region between solid-state physics and quantum optics with the aim of probing quantum mechanics in macroscopic mechanical structures. We employ superconducting circuits to address fundamental questions like, the preparation of phonon number states in the vibrational mode and the conversion of quantum states between the mechanical element and the microwave domain. The initial successful experiments of the group include hybrid devices based on superconducting transmon qubits, microwave resonators and mechanical nano-string resonators. You should aim at the next, important step to integrate the nanomechanical string resonator into the transmon qubit to experimentally realize a new type of interaction in light matter coupling.

We are looking for a highly motivated master student joining this project. The goal of your thesis is the development of hybrid devices based on superconducting transmon qubits, nanomechanical string-resonators and superconducting microwave resonators as well as their spectroscopy. This includes the design and fabrication of these devices, where you will use state of the art simulation and nano-fabrication techniques. The second main aspect of your thesis is their investigation using highly sensitive microwave spectroscopy techniques in a low-temperature environment.
