Silicon spin qubits stand out due to their very long coherence times, compatibility with
industrial fabrication, and prospect to integrate classical control electronics. To achieve a …

Current complementary metal-oxide semiconductor (CMOS) quantum processors employ
dense gate arrays to define quantum dots, making them susceptible to crosstalk from …

The usual models for electrical spin manipulation in semiconductor quantum dots assume
that the confinement potential is separable in the three spatial dimensions and that the ac …

Bottom-up grown nanomaterials play an integral role in the development of quantum
technologies but are often challenging to characterise on large scales. Here, we harness …

We use the tip of an atomic force microscope (AFM) to charge floating metallic gates defined
on the surface of a Si/Si Ge heterostructure. The AFM tip serves as an ideal and movable …

A quantum system constrained to a degenerate energy eigenspace can undergo a nontrival
time evolution on adiabatic driving, described by a non-Abelian Berry phase. This type of …
