We demonstrate proof-of-principle of shuttling a single electron by a gate induced propagating wave-potential in Si/SiGe termed conveyor mode [3] shuttling. Independent from its length only four sinusoidal control signals and low tuning effort is required. We transfer a single electron over 420 nm and observe a high single-electron shuttling fidelity of 99.42±0.02 % including a reversal of direction. Measuring the sensor response while transferring the electron enables us to detect the electron motion. Our shuttler can be readily embedded in industrial fabrication of Si/SiGe qubit chips and paves the way to solving the signal-fanout problem for a fully scalable semiconductor quantum-computing architecture.
