Prof. Shang-Da Jiang is a full professor in the Spin-X Institute at South China University of Technology. He has obtained the PhD in the College of Chemistry and Molecular Engineering at Peking University in 2011, and his PhD thesis was awarded National Excellent Doctorial Dissertation of China in 2013. He was awarded with the RIGAKU-ACCC Rising Star award, as well as the International Award for Creative Work of Japan Society of Coordination Chemistry in 2022, and obtained the National Science Fund of China for Distinguished Young Scholars in 2023. Prof. Jiang’s present research interests are the quantum coherence manipulation of magnetic molecules and EPR spectroscopy.

 

Quantum information technology can realize a new information processing based on quantum mechanics principles. Chemical design can control the quantum behavior of magnetic molecules and obtain a larger Hilbert space. Therefore, studying the quantum coherence of magnetic molecules, performing novel and complex quantum coherence manipulations, and trying to use magnetic molecules for quantum computing are important contents of quantum information materials chemistry.

 

The spin-optical interface, enabling active control of spin states in materials, has attracted widespread interest. Circularly polarized light can be used to directly inject angular momentum into spin carriers by optical excitation, providing a robust means of spin polarization and readout. In this talk, I will present our nearest results about a home-built cryogenic confocal optically-detected magnetic resonance (ODMR) spectrometer, realizing the optical spin polarization of rare-earth ions in solid and conducting pulsed ODMR experiments based thereon.
