Quantum Advancement through Sweden–Singapore Integration (QUASI)

Important results from the project

The main objectives were achieved. The same QiB1 device from ConScience was measured at the WACQT Quantum Technology Testbed in Gothenburg and NQFF in Singapore, then remeasured in Gothenburg after return. Qubit frequencies and coherence times were broadly stable, with a frequency shift observed for one qubit. The project strengthened collaboration and knowledge exchange between the laboratories, and the benchmarking can be used as a basis for development of global standards for hardware tests.

Expected long term effects

Common measurement methods and experiences of transportation can contribute to more reliable and comparable characterization of quantum hardware within the consortium, and globally in the development of standards. The collaboration will continue with a planned Horizon Europe application on the manufacture and testing of an amplifier in both laboratories. In a larger perspective, the project can facilitate the exchange of services within test infrastructure for Swedish and Singaporean companies.

Approach and implementation

ConScience manufactured the QiB1 device, which was measured in Gothenburg, shipped to NQFF in Singapore, and re-measured after return transport. The laboratories shared the Tergite software and selected measurement equipment. The collaboration was supported by training, digital meetings, and physical meetings in both countries. The ISP´s dual-use product license review delayed the schedule by approximately two months, still the measurements were completed as planned.
