QUEST Lab
Welcome to the Quantum Engineering and Simulation Theory (QUEST) Lab in the Department of Electrical & Computer Engineering and the Department of Computer Science at NC State University in Raleigh, North Carolina!
Our research aims at developing quantum-information-science-inspired algorithms and framework to tackle long-lasting challenges in physical sciences and engineering, with a focus on quantum algorithms and simulation, hybrid continuous-discrete-variable quantum computing, and quantum engineering.
We are always looking for motivated students and scholars to join us to explore the exciting frontier of quantum information science and engineering!

| Nov 25, 2025 | Our tutorial on Hybrid Continuous-Discrete-Variable Quantum Computingon and our paper on COMPAS: A Distributed Multi-Party SWAP Test for Parallel Quantum Algorithms both have been accepted to ASPLOS ‘26 (the ACM International Conference on Architectural Support for Programming Languages and Operating Systems)! COMPAS is the first distributed implementation of the multi-party SWAP test on quantum computers, by extending the leading construction to the distributed setting while preserving optimal circuit depth and memory overhead. As distributed quantum computing is becoming increasingly important, our work establishes efficient implementation of core primitives for future production-level deployment of distributed quantum computational science! This work is done in collaboration with Brown University, Yale University, QuEra Inc., and MIT. Congratulations to the team and see you in Pittsburg! |
