QLSI - Quantum Large-Scale Integration with Silicon

QLSI - Quantum Large-Scale Integration with Silicon

Project duration: 2020 - 2024

The QLSI project aims to develop a scalable technology for silicon qubits for quantum computing. Silicon qubits can be driven and read out quickly and are ideally suited for quantum computing due to their small size, high Q-factor and compatibility with industrial manufacturing processes. Silicon qubits have been successfully demonstrated many times; the project is now about developing a scalable technology for later industrial implementation and demonstrating a 16-qubit chip.

With the Center Nanelectronic Technologies, Fraunhofer IPMS contributes a 4000 m² clean room and its expertise in state-of-the-art, industry-compatible CMOS semiconductor manufacturing on 300-mm wafer standard. This concerns, for example, manufacturing processes for nanostructuring, but also material development and electrical control from the CMOS area. In close cooperation with Infineon Dresden, RWTH Aachen University and FZ Jülich, the first qubit demonstrators on wafer level are realized in the project.


This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreements 951852.
