Fraunhofer Institute for Applied Solid State Physics IAFFrom February 21 to 23, 2024, the 5th consortium meeting of the QUASAR project took place at Fraunhofer IAF. A comprehensive program offered participants from the partner institutions and companies the opportunity to exchange on the status and next steps in the project. Presentations, discussions, a tour of the new cryogenic measurement system at Fraunhofer IAF and a poster session enabled the participants to further intensify their collaboration.
Development of a scalable semiconductor quantum processor is progressing
02/28/2024 / 5th QUASAR consortium meeting
The 5th consortium meeting of the QUASAR project took place at Fraunhofer IAF from February 21 to 23, 2024.
QUASAR aims to develop a semiconductor quantum processor with a shuttling-based scalable architecture. Silicon/silicon germanium quantum wells are used as the technological basis for the realization of qubits. The researchers use electron shuttling to connect several qubits in a scalable manner and achieve more stable coherences. This approach allows control electronics and feed lines to be constructed more flexibly together with qubits.
The cooperation between universities, industrial partners and application-oriented research institutes ensures that QUASAR is driving forward the establishment of a complete value chain for the quantum hardware to be developed with industrial transfer potential in Germany. Fraunhofer IAF contributes know-how and infrastructure for the pre-characterization of qubit devices to the project goal. With the help of an automatic cryogenic wafer prober, which characterizes up to 300 mm wafers at 2 K, the researchers can provide fast and statistically meaningful feedback on the quality of components.
