Research Summary

My research interests lie in the areas of both compiler and modeling of quantum systems. Specifically, I am currently working on building efficient quantum computing simulation Eco-system.
This project includes: i) leveraging innovative system optimizations to simulate large and complex quantum circuits. Ii) Developing both front-end and back-end quantum compiler supports for complex quantum circuits. Iii) Building software-hardware co-optimizations for domain-specific (e.g., quantum chemical applications) quantum applications. Iv) Exploring heterogeneous system designs that consist of quantum devices and classical devices. In the long term, I am also interested in quantum error modeling and compiler-guided quantum circuit transformation.
