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…
High- membrane resonators using ultra-high-stress crystalline TiN films
Yuki Matsuyama, Shotaro Shirai, Ippei Nakamura +6
High-quality-factor () mechanical resonators are essential components for precise sensing and control of mechanical motion at a quantum level. While amorphous materials such as…
Superconducting surface trap chips for microwave-driven trapped ions
Yuta Tsuchimoto, Ippei Nakamura, Shotaro Shirai +1
Microwave-driven trapped ion logic gates offer a promising avenue for advancing beyond laser-based logic operations. In future microwave-based operations, however, the joule heat p…
Compact atom source using fiber-based pulsed laser ablation
Alto Osada, Ryuta Tamaki, Wenbo Lin +2
We designed, demonstrated, and characterized an atom source based on fiber-based pulsed laser ablation. By using commercially available miniature lens system for focusing nanosecon…
