Hi there! Welcome to the Tung group website.
Our research group, based at National Tsing Hua University in Taiwan, explores the frontiers of quantum physics with ultracold atoms and trapped ions. We are working to exploit these two distinct systems for the development of the next generation of technologies, such as quantum simulation, quantum sensing, and quantum metrology. If you like to know more about our research, please contact us.

![43ca+](Images/43Ca+.png)
A pure crystal of nine 43Ca+ ions, prepared using isotope-selective ionization and isotope-specific parametric excitations. 43Ca is a rare isotope of calcium, showing up only once in every 740 calcium atoms. Find our manuscript at ArXiv: 2309.11809
