High-precision real-space simulation of electrostatically-confined few-electron states
Christopher R. Anderson, Mark F. Gyure, Sam Quinn +3
In this paper we present a computational procedure that utilizes real-space grids to obtain high precision approximations of electrostatically confined few-electron states such as…
Detuning Axis Pulsed Spectroscopy of Valley-Orbital States in Si/SiGe Quantum Dots
Edward H. Chen, Kate Raach, Andrew Pan +16
Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximiz…
Magnetic Gradient Fluctuations from Quadrupolar Ge in Si/SiGe Exchange-Only Qubits
J. Kerckhoff, B. Sun, B. H. Fong +14
We study the time-fluctuating magnetic gradient noise mechanisms in pairs of Si/SiGe quantum dots using exchange echo noise spectroscopy. We find through a combination of spectral…
Split-Gate Cavity Coupler for Silicon Circuit Quantum Electrodynamics
F. Borjans, X. Croot, S. Putz +12
Coherent charge-photon and spin-photon coupling has recently been achieved in silicon double quantum dots (DQD). Here we demonstrate a versatile split-gate cavity-coupler that allo…
Resonant Exchange Operation in Triple-Quantum-Dot Qubits for Spin-Photon Transduction
Andrew Pan, Tyler E. Keating, Mark F. Gyure +5
Triple quantum dots (TQDs) are promising semiconductor spin qubits because of their all-electrical control via fast, tunable exchange interactions and immunity to global magnetic f…
Spin-Blockade Spectroscopy of Si/SiGe Quantum Dots
A. M. Jones, E. J. Pritchett, E. H. Chen +15
We implement a technique for measuring the singlet-triplet energy splitting responsible for spin-to-charge conversion in semiconductor quantum dots. This method, which requires fas…
