Deterministic assembly of gatemon qubits using dielectrophoresis

This thesis focuses on fabrication and characterization of a four-qubit nanowire-based transmon device using dielectrophoresis. In this method, nanowires suspended in solution are assembled on pre-patterned electrodes on the chip in a deterministic manner. To date, the main challenge to fabricating multi-qubit devices based on nanowire Josephson junctions has been random placement of the nanowires on the device chip. Dielectrophore-sis provides possibility to overcome this challenge by means of large scale diposition of nanowires on pre-patterned electrodes and thus opens a new path to fabricating multi-qubit generation devices.
