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
The paper proposes electron pair interferometry (EPI) to enable robust control and measurement of nuclear spin qubits in silicon, using shuttled electron pairs to transfer nuclear…

Learning parameter curves in feedback-based quantum optimization algorithms
Vicente Peña Pérez, Matthew D. Grace, Christian Arenz +1
Feedback-based quantum algorithms (FQAs) operate by iteratively growing a quantum circuit to optimize a given task. At each step, feedback from qubit measurements is used to inform…
