Performance of the spin qubit shuttling architecture for a surface code implementation
An arXiv preprint examines a surface-code architecture in which electron spin qubits are physically moved between quantum dots. It uses a standard noise model to quantify how shuttling-induced errors affect the code's logical performance and its prospects for scaling to useful register sizes.

Within two years, silicon spin-qubit teams could use this framework to set shuttling fidelity targets for early surface-code experiments, narrowing layout and material choices before expensive multi-qubit shuttling hardware is built.
The study applies a standard noise model to shuttling errors in surface-code architectures; several academic and industry groups already demonstrate spin qubit shuttling with measurable error rates, so the next step is comparing model predictions with device-level shuttling data to guide near-term devices.
