European Conference on Trapped Ions (ECTI)

Electronic control methods, where quantum gates are implemented without lasers, hold great potential for trapped-ion quantum computing due to their low fundamental errors and the ease of scalability. In this work, we demonstrate a new electronic control method, where addressed single-qubit rotations are implemented by localized AC electric fields, generated by trap electrodes. We demonstrate theoretically and experimentally how this tool enables local single-qubit control in a multizone trap, using only small voltages and existing trap structures. Finally, we discuss how electronic control techniques enable large-scale integration of trapped-ion quantum computers with scalable fabrication processes.
