Noise-resilient and Scalable Quantum Error Correction for Nuclear Spin Qubits in Silicon with Electron Shuttling
Wayne M. Witzel, Matthew D. Grace, Dwight R. Luhman
Nuclear spin qubits in silicon are well-isolated from their environment. Consequently, they have very long lifetimes and low sensitivity to noise, but this also suggests that contr…

Predicting the Slow Drift of Nuclear Spin Noise in Semiconductor Spin Qubits
Wayne M. Witzel, Jesse J. Lutz, Matthew D. Grace +3
The dynamics of a nuclear spin bath generates magnetic noise that is a key contributor to the decoherence of electron spin qubits in electrostatically-defined quantum dots. In this…

Using a high-fidelity numerical model to infer the shape of a few-hole Ge quantum dot
Mitchell Brickson, N. Tobias Jacobson, Andrew J. Miller +4
The magnetic properties of hole quantum dots in Ge are sensitive to their shape due to the interplay between strong spin-orbit coupling and confinement. We show that the split-off…
