Path integral simulation of exchange interactions in CMOS spin qubits
Jesús D. Cifuentes, Philip Y. Mai, Frédéric Schlattner +5
The boom of semiconductor quantum computing platforms created a demand for computer-aided design and fabrication of quantum devices. Path integral Monte Carlo (PIMC) can have an im…
Multielectron dots provide faster Rabi oscillations when the core electrons are strongly confined
H. Ekmel Ercan, Christopher R. Anderson, S. N. Coppersmith +2
Increasing the number of electrons in electrostatically confined quantum dots can enable faster qubit gates. Although this has been experimentally demonstrated, a detailed quantita…
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…
Coherent control and spectroscopy of a semiconductor quantum dot Wigner molecule
J. Corrigan, J. P. Dodson, H. Ekmel Ercan +12
Multi-electron semiconductor quantum dots have found wide application in qubits, where they enable readout and enhance polarizability. However, coherent control in such dots has ty…
Measurement-free implementations of small-scale surface codes for quantum dot qubits
H. Ekmel Ercan, Joydip Ghosh, Daniel Crow +4
The performance of quantum error correction schemes depends sensitively on the physical realizations of the qubits and the implementations of various operations. For example, in qu…
