This study demonstrates high-fidelity single-spin shuttling in silicon using electric gate potentials. The researchers report shuttling an electron over an effective distance of 10 micrometers with an average fidelity of 99% using a traveling wave potential. They compare two shuttling methods: bucket-brigade (BB) and conveyor-mode (CV). The CV method, which uses a traveling wave potential, shows significantly better spin coherence than BB. The study also evaluates the performance of a novel two-tone conveyor method, which uses two sine waves with different frequencies to achieve higher shuttling speeds and improved fidelity. The results show that the two-tone conveyor allows for faster and more accurate shuttling, with a fidelity of 99.07% over a distance of 10 micrometers. The study also demonstrates that the shuttling fidelity is mainly limited by the ratio between the shuttling time and the spin dephasing time. The results highlight the potential of electron shuttling for future large-scale semiconductor quantum processors, enabling both within and between qubit arrays. The study provides insights into the challenges and opportunities of high-fidelity quantum interconnects between spin qubits.This study demonstrates high-fidelity single-spin shuttling in silicon using electric gate potentials.
