Spin qubits in silicon have emerged as a promising candidate for a scalable quantum computer due to their small footprint, long coherence times, and their compatibility with advanced semiconductor manufacturing. However, all known spin qubit material hosts come with specific challenges, that limit the performance of quantum information...

We engineer planar Ge/SiGe heterostructures for low disorder and quiet hole quantum dot operation by positioning the strained Ge channel 55 nm below the semiconductor/dielectric interface. In heterostructure field effect transistors, we measure a percolation density for two-dimensional hole transport of 2.1 × 10 10 cm−2 , indicative of a very...
