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 are always looking for motivated students and scholars to join us to explore the exciting frontier of quantum information science and engineering! Interested students and scholars are encouraged to contact Prof. Yuan Liu.

News

Oct 4, 2024 Prof. Liu and NC State led team have received a $10.6M award from the U.S. Department of Energy to investigate the utility of hybrid quantum processors (Press Release). Congratulations to the entire team (NC State, Rutgers University, PNNL, LBNL, NASA Ames, UMass Amherst) and we are excited to embark on the journey!
Sep 9, 2024 Prof. Liu is attending IEEE Quantum Week QCE24 from September 15 - 20 in Montreal, Canada. He will also give an invited talk at the Advancing Quantum Computation Beyond Gate-Model (BGM2024) Workshop at the University of Maryland, College Park on October 7!
Aug 20, 2024 The QUEST group welcome Ph.D. students Shariful Islam and Elin Das to join us! We are also glad to host visiting scholar Xi Lu from Zhejiang University!
Aug 19, 2024 Kudos to Prof. Liu for being awarded the seed funding from the Center for Robust Quantum Simulation at the University of Maryland, together with Prof. Victor Albert (UMD and NIST). Excited to explore molecular conical intersections!
Aug 11, 2024 Congratulations to Prof. Liu, Prof. Huiyang Zhou, Prof. Frank Mueller, and the QACTI team, led by Duke University, being selected as one of the five NSF National Quantum Virtual Laboratory pilot projects. We look forward to pushing the boundaries of quantum computing with trapped ions!
