Huo Chen

Affiliation and Research Interests

I am a postdoctoral scholar at the Lawrence Berkeley National Laboratory, working in the Applied Computing for Scientific Discovery Group of the Applied Mathematics and Computational Research Division within the Computing Sciences Directorate. My primary research focus is on the theories and numerical methods of open quantum systems. In my previous work, I developed state-of-the-art models for open quantum systems that are applicable to current quantum devices. Currently, I am engaged in developing innovative quantum algorithms to accurately simulate the dynamics of open quantum systems. (Disclaimer: this paragraph is written by ChatGPT.)
