Jiaqi Leng

Welcome to Jiaqi Leng's homepage.

I am a second-year doctoral student in the Department of Mathematics (track: applied math) at the University of Maryland, College Park. I am also affiliated to QuICS. I am interested in quantum computing and quantum information. I'm fortunate to be advised by Xiaodi Wu.

Prior to Maryland, I graduated in June 2019 with Bachelor of Science (First Class Honours) from the Faculty of Science, the University of Hong Kong. My Bachelor's thesis is Turbulence in one spatial dimension, advised by Tak Kwong WONG. I was also a full-year exchange student at the University of Chicago from 2017 to 2018.

My name in Chinese: 冷佳奇.




I aim to apply advanced mathematics to the design and understanding of quantum algorithms, especially quantum simulations and quantum machine learning. I am particularly interested in near-term and mid-term pratical applications of quantum computing in physics, chemistry, material sciences, and optimizations. I am also intrigued by quantum information geometry and its potential application to quantum algorithms.
