Published in Nature Electronics: A hole spin qubit in a finFET above 4 Kelvin

One of the greatest challenges in quantum computing is scaling. Classical nm-scale fin field-effect transistors (FinFETs) have scaled to billions of transistors on a silicon chip. Here, we operate a silicon FinFET as a hole spin qubit above…
