Phase-Space Topology in a Single-Atom Synthetic Dimension
Kyungmin Lee, Sunkyu Yu, Jiyong Kang +5
We investigate topological features in the synthetic Fock-state lattice (FSL) of a single-atom system described by the quantum Rabi model. By diagonalizing the Hamiltonian, we iden…
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…
A silicon-based ion trap chip protected from semiconductor charging
Daun Chung, Kwangyeul Choi, Woojun Lee +15
Silicon-based ion trap chips can benefit from existing advanced fabrication technologies, such as multi-metal layer techniques for two-dimensional architectures and silicon photoni…
Photo-induced charge carrier dynamics in a semiconductor-based ion trap investigated via motion-sensitive qubit transitions
Woojun Lee, Daun Chung, Honggi Jeon +8
Ion trap systems built upon microfabricated chips have emerged as a promising platform for quantum computing to achieve reproducible and scalable structures. However, photo-induced…
Micromotion compensation of trapped ions by qubit transition and direct scanning of dc voltages
Woojun Lee, Daun Chung, Jiyong Kang +4
Excess micromotion is detrimental to accurate qubit control of trapped ions, thus measuring and minimizing it is crucial. In this paper, we present a simple approach for measuring…
