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…

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…
