Hello ~ I’m Haimeng Zhao /haɪ məŋ dʒaʊ/ 赵海萌, a PhD student in Physics at Caltech, advised by John Preskill and Hsin-Yuan Huang.

I’m deeply fascinated by how the universe works and how we can possibly understand it. So I started working at the intersection of Physics and Learning, exploring the physical nature of learning and computation.

Three overarching questions motivate my work:

1. How do physical laws impact our ability to learn and how to harness them?
2. How does our (in)ability to learn impact our perception of the physical reality?
3. What is the ultimate physical limit of learning and computation?

I draw ideas from theoretical physics, computer science, and machine learning to answer these questions.

I also worked as a Student Researcher at Google Quantum AI. Before Caltech, I received my Bachelor’s degree in Mathematics and Physics with Honours from Tsinghua University. I was an undergrad research fellow in John Preskill’s group at IQIM, Caltech and an exchange student in Giuseppe Carleo’s group at EPFL in Switzerland. At Tsinghua, I worked on quantum information with Dong-Ling Deng at IIIS and AI for Astronomy with Wei Zhu.

Research Interests: Quantum Information, Computation, and Many-body Physics; AI + Physics.
