Chien-Yuan (Ted) Chang is currently an assistant professor at the Institute of Electrical Engineering and Department of Physics at National Tsing Hua University (NTHU). 

Before joining NTHU, I have been working as a postdoctoral researcher since 2019 at the Semiconductor Quantum Information Device Research Team and Quantum Functional System Research Group in the RIKEN Center for Quantum Computing in Japan. Prior to this position, from 2018 to 2019, I worked as a project researcher in the Tarucha Laboratory at the University of Tokyo.

My research primarily focuses on quantum state transfer and coherent entanglement transformation between distant qubits. Currently, I am involved in a project that investigates the transfer of entangled photon pairs to photon and semiconductor spin qubits through a photon/spin interface. This project serves as a demonstration for the application of quantum internet. Additionally, spin qubits have a wide range of applications in quantum optics and quantum technology, including quantum communication, quantum repeaters, and distributed quantum computation.

Before relocating to Japan, I earned my B.E. in Electrical Engineering from National Taiwan University (NTU) and my Ph.D. in Physics from the Georgia Institute of Technology. During my Ph.D., I worked on various projects, including trapped-ion qubits under the guidance of Prof. Kenneth Brown, quantum stability analysis and coherent quantum feedback with photonic qubits under Prof. Loic Lanco and Prof. Pascale Senellart, and photonic information processing with nonlinear optics under Prof. David Citrin.
