Mode-Selective Micromotion Compensation via Coherent Excitation of a Ground-State-Cooled Motional Mode
Tetsu Kinase, Ippei Nakamura, Atsushi Noguchi
Excess micromotion induced by stray DC electric fields limits the control fidelity of trapped-ion experiments. Various techniques have been developed to detect and compensate ion d…
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…
Trapping an Atomic Ion using Time-Division Multiplexed Digital-to-Analog Converters
Ryutaro Ohira, Masanari Miyamoto, Shinichi Morisaka +4
Independent control of numerous electrodes in quantum charge-coupled device architectures presents a significant challenge for wiring and hardware scalability. To address this issu…
Multiplexed Control at Scale for Electrode Arrays in Trapped-Ion Quantum Processors
Ryutaro Ohira, Shinichi Morisaka, Ippei Nakamura +2
The scaling up of trapped-ion quantum processors based on the quantum charge-coupled device (QCCD) architecture is difficult owing to the extensive electronics and high-density wir…
