A quantum-charge-coupled-device trapped-ion quantum computer utilizing all-electronic control

We present our vision for large-scale, parallel control of trapped-ion qubits using chip-integrated electric and magnetic fields. Our architecture enables efficient parallelization of gate operations and shuttling of ions on a surface-electrode trap chip with junctions, implementing a quantum charge-coupled device with high gate fidelities [1] and a straightforward path to scalability [2]. We outline how single- and two-qubit gates can be performed in parallel, and show data from prototype devices.
