Two-dimensional hole gases


Self-assembled nanostructures are very promising structures for studying fundamental aspects of spin physics, realizing a small number of qubits and study hybrid superconducting-semiconducting devices. However, it is widely believed that if one is interested in moving towards the realization of multiple qubits, QDs created in heterostructures offer great advantages in terms of scalability. In our group we work with SiGe heterostructures which lead to the confinement of holes in a Ge quantum well.
