Characterization and cancellation of power-line-induced motional-mode frequency noise in a trapped-ion system
Jaehun You, Jiyong Kang, Kyunghye Kim +2
The stability of motional-mode frequency is essential for realizing high-fidelity quantum gates in trapped-ion quantum computing. While broadband Gaussian noise has been extensivel…

Multimode Phonon-Number Measurement and Single-shot Superparity Measurement using Dispersive Shifts in a Trapped Ion
Wonhyeong Choi, Jiyong Kang, Kyunghye Kim +3
Dispersive shifts are a widely used tool for bosonic readout and control in circuit quantum electrodynamics, yet they remain relatively unexplored in trapped-ion motional systems.…
