Left: schematic of a fin field-effect transistor (finFET) with triangular fin. Right: Transmission electron microscope image of a silicon finFET device cross-section: voltages at the titanium-nitride gate (blue) are used to accumulate quantum dots at the silicon/silicon-oxide (purple/black) interface in the fin. In Basel, spin qubits, the building block of a spin-based quantum computer, are energized and studied in such quantum dots.

The Quantum Large Scale Integration (QLSI) project brings together 19 top European groups to focus on developing highly scalable quantum processors in silicon, and marks a recent addition to the EU’s Quantum Flagship, a €1 Billion R&D initiative launched in 2018 and running for 10 years.
