Welcome to the QUEST Lab!
We are 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 have two postdoctoral positions available on hybrid continuous-discrete variable quantum computing. Interest candidates are encouraged to apply here. We are always looking for motivated students and scholars to join us to explore the exciting frontier of quantum information science and engineering!
