A LITTLE ABOUT ME

Weikang Li 李炜康

At the meeting point of quantum physics and machine learning.

01 /Hello, I'm Weikang.

I am Weikang Li (李炜康), a physicist working on quantum information and machine learning. I received my Ph.D. in Physics from Tsinghua University in 2025, advised by Prof. Dong-Ling Deng at the Center for Quantum Information, IIIS. Before that, I studied Applied Physics at the School of the Gifted Young, USTC, receiving my B.S. in 2020.
