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.…
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…
Two-Mode Bosonic State Tomography with Single-Shot Joint-Parity Measurement of a Trapped Ion
Honggi Jeon, Jiyong Kang, Wonhyeong Choi +3
The full characterization of a continuous-variable quantum system is a challenging problem. For the trapped-ion system, a number of methods of measuring the quantum states have bee…
Radio-Frequency Pseudo-Null Induced by Light in an Ion Trap
Daun Chung, Yonghwan Cha, Hosung Shon +12
In a linear radio-frequency (rf) ion trap, the rf null is the point of zero electric field in the dynamic trapping potential where the ion motion is approximately harmonic. When di…
