Silicon/silicon-germanium quantum well heterostructures are a leading materials system for hosting semiconducting quantum dot qubits.  Compared to the silicon metal-oxide-semiconductor materials stack used in current classical computers, Si/SiGe has the advantage that the qubits are confined near a high-quality epitaxial interface that is relatively far from defects that can degrade performance. This talk will discuss our theoretical work that shows that compositional disorder in the SiGe plays a crucial role and demonstrates how this understanding can be exploited to optimise quantum dot qubits in Si/SiGe .

Professor Coppersmith’s seminar is part of her tour of Australia as this year’s AIP’s 2024 Women in Physics Lecturer.

As part of her tour, Prof. Coppersmith will also present a public lecture in Melbourne.
