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.…
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…
Efficient Quantum Frequency Conversion of Ultra-Violet Single Photons from a Trapped Ytterbium Ion
Seungwoo Yu, Kyungmin Lee, Sumin Park +4
Ion trap system is a leading candidate for quantum network privileged by its long coherence time, high-fidelity gate operations, and the ion-photon entanglement that generates an i…
