Superconducting qubit devices: fabrication suite — •Wei Liu, Kok Wai Chan, Tianyi Li, Johannes Heinsoo, Vasilii Sevriuk, Caspar Ockeloen-Korppi, Jani Tuorila, Juha Hassel, Juha Vartiainen, Kuan Yen Tan, Jan Goetz, and Mikko Mottonen — IQM Finland Oy, Vaisalantie 6, 02130 Espoo, Finland
Scalable quantum computing architecture and fabrication processes have been a hot research topic in the past decade. We focus on the realization of a quantum computer based on superconducting qubits with a fast qubit reset and initialization techniques, utilizing a quantum- circuit refrigerator. We present the fabricated devices and results achieved to date, which includes resonators with high quality factors, >106, long qubit lifetime > 0.02 ms and 3D integration techniques such as airbridges.
