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…
Correcting coherent quantum errors by going with the flow
Wayne M. Witzel, Anand Ganti, Tzvetan S. Metodi
The performance of a given quantum error correction (QEC) code depends upon the noise model that is assumed. Independent Pauli noise, applied after each quantum operation, is a sim…
Verifying Quantum Phase Estimation (QPE) using Prove-It
Wayne M. Witzel, Warren D. Craft, Robert Carr +1
The general-purpose interactive theorem-proving assistant called Prove-It was used to verify the Quantum Phase Estimation (QPE) algorithm, specifically claims about its outcome pro…
The remarkable prospect for quantum-dot-coupled tin qubits in silicon
Wayne M. Witzel, Jesse J. Lutz, Dwight R. Luhman
Spin- Sn nuclei in a silicon semiconductor could make excellent qubits. Nuclear spins in silicon are known to have long coherence times. Tin is isoelectronic w…
Multi-qubit gates protected by adiabaticity and dynamical decoupling applicable to donor qubits in silicon
Wayne M. Witzel, Inès Montaño, Richard P. Muller +1
We present a strategy for producing multi-qubit gates that promise high fidelity with minimal tuning requirements. Our strategy combines gap protection from the adiabatic theorem w…
Measuring central-spin interaction with a spin bath by pulsed ENDOR: Towards suppression of spin diffusion decoherence
S. J. Balian, M. B. A. Kunze, M. H. Mohammady +4
We present pulsed electron-nuclear double resonance (ENDOR) experiments which enable us to characterize the coupling between bismuth donor spin qubits in Si and the surrounding spi…
