Hi! I am a third-year graduate student in computer science at Institute of Computing Technology, Chinese Academy of Sciences, supervised by Xiaoming Sun and Jialin Zhang. I have a broad interest in theoretical computer science and quantum computing. Recently, I am working on quantum cryptography and distributed quantum computing.

News: I am looking for PhD positions starting in 25 Fall.

Coding

I am one of the core contributors to the open-source SDK for quantum computation, which is analogous to Qiskit but specialized in quantum circuit compiling.

Besides, I participated in International Collegiate Programming Contest (ICPC) back when I was an undergrad. We won Gold Medal at ICPC Asia Regional (Jinan) and Silver Medal at ICPC Asia East-Continent Final. My max Codeforces rating is 2083.

Misc

I play piano. My (current) favorite composer is Nikolai Kapustin.
