This study presents a method for operating semiconductor quantum processors using hopping spins, achieving high-fidelity quantum gates and long coherence times. The researchers demonstrate that hopping-based quantum logic can be implemented with single-spin semiconductor qubits, where spins are transferred between quantum dots with site-dependent spin quantization axes. This approach enables high-fidelity single-qubit gates (99.97%), coherent shuttling (99.992%), and two-qubit gates (99.3%), which are predicted to support quantum error correction. The method uses discrete digital control signals, avoiding the need for high-frequency resonant control, which can cause crosstalk and heating. The study also shows that hopping spins can be used for elegant tuning by statistically mapping the coherence of a 10-quantum dot system. The results suggest that dense quantum dot arrays with sparse occupation could enable efficient and high-connectivity qubit registers. The work highlights the potential of hopping-based quantum control for scalable quantum processors, with applications in error correction and other quantum computing tasks. The study also addresses challenges in coherence, control, and quantum link creation, and demonstrates the feasibility of high-fidelity quantum operations in low magnetic fields. The results are supported by detailed experimental and theoretical analysis, including gate fidelity measurements, coherence times, and error modeling. The study provides a foundation for further exploration of hopping-based quantum processors in various platforms.This study presents a method for operating semiconductor quantum processors using hopping spins, achieving high-fidelity quantum gates and long coherence times.
