Strong electron-electron interactions in Si/SiGe quantum dots
H. Ekmel Ercan, S. N. Coppersmith, Mark Friesen
Interactions between electrons can strongly affect the shape and functionality of multi-electron quantum dots. The resulting charge distributions can be localized, as in the case o…
Charge-noise resilience of two-electron quantum dots in Si/SiGe heterostructures
H. Ekmel Ercan, Mark Friesen, S. N. Coppersmith
The valley degree of freedom presents challenges and opportunities for silicon spin qubits. An important consideration for singlet-triplet states is the presence of two distinct tr…
Valley splittings in Si/SiGe quantum dots with a germanium spike in the silicon well
Thomas McJunkin, E. R. MacQuarrie, Leah Tom +11
Silicon-germanium heterostructures have successfully hosted quantum dot qubits, but the intrinsic near-degeneracy of the two lowest valley states poses an obstacle to high fidelity…
How valley-orbit states in silicon quantum dots probe quantum well interfaces
J. P. Dodson, H. Ekmel Ercan, J. Corrigan +7
The energies of valley-orbit states in silicon quantum dots are determined by an as yet poorly understood interplay between interface roughness, orbital confinement, and electron i…
