Gating a Quantum Dot through the Sequential Removal of Single Electrons from a Nanoscale Floating Gate

AO Denisov, G Fuchs, SW Oh, JR Petta - PRX Quantum, 2023 - APS
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 …

Protocols to measure the non-Abelian Berry phase by pumping a spin qubit through a quantum-dot loop

B Kolok, A Pályi - Physical Review B, 2024 - APS
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 …
