"Mobile qubits offer a promising alternative by enabling flexible connectivity between qubits, thus reducing the overhead associated with error correction schemes."
"Gate-defined semiconductor spin qubits have emerged as a promising candidate due to their compelling combination of extended coherence times and high-fidelity operations."
"The conveyor shuttling method achieved a 99.5% fidelity when shuttling across an effective 10-μm distance in less than 200 ns."
"Scalable mobile spin qubit architectures based on conveyor-mode shuttling enable efficient resource management and interaction between qubits."
Quantum computing can solve complex problems beyond classical computers. High connectivity between qubits is essential for effective error correction, but traditional architectures limit interactions. Mobile qubits provide flexible connectivity, reducing error correction overhead. Gate-defined semiconductor spin qubits are promising due to their extended coherence times, high-fidelity operations, and compatibility with semiconductor manufacturing. Recent experiments using a conveyor shuttling method achieved 99.5% fidelity in transporting spin qubits, suggesting scalable architectures for efficient qubit transport and interaction.
