Cryogenic Time-Division-Multiplexed Voltage Control for Scalable Trapped-Ion Quantum Processors
Ryutaro Ohira, Shinichi Morisaka, Yoshinori Kurimoto +4
Trapped-ion quantum computers based on the quantum charge-coupled device architecture require on the order of ten trap electrodes per qubit, making the number of vacuum feedthrough…
