Jiaqi (Jimmy) Leng

I am a Simons Quantum Postdoctoral Fellow at Simons Institute for the Theory of Computing at UC Berkeley, hosted by Umesh Vazirani and Lin Lin. I got my Ph.D. from the University of Maryland in 2024, where I was fortunate to be advised by Xiaodi Wu. My name in Chinese: 冷佳奇.
My research focuses on quantum algorithms for continuous optimization and scientific computing. Specifically, I advocate Hamiltonian-oriented quantum algorithm design, a new paradigm in quantum computation that emphasizes both provable quantum speedups and realistic hardware implementability. I am particularly interested in the following topics:
- Theoretical foundation and design of quantum algorithms,
- Resource-efficient deployment of quantum algorithms,
- Infrastructure (e.g., software toolchains, benchmark, etc.) for quantum applications.
