Welcome to the QuEST @ NC State

We are the Quantum Engineering and Simulation Theory (QuEST) group in the Department of Electrical and 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 discrete-continuous-variable quantum information processing, and quantum engineering. We have Ph.D. positions available. We are always looking for motivated Master’s and undergraduate students to join us. Interested students and scholars are encouraged to contact me.


Jan 7, 2024 I am teaching a new graduate-level course on Quantum Algorithms for Physical Sciences this coming semester at NC State! See here for more details.
Nov 22, 2023 Our paper on Single-shot quantum signal processing interferometry is posted on arXiv, where we proposed a general algorithmic framework, quantum signal processing interferometry (QSPI), for quantum sensing at the fundamental limits of quantum mechanics, i.e., the Heisenberg sensing limit, by generalizing Ramsey-type interferometry.
Aug 11, 2023 I am attending ACS Fall Meeting 2023 August 13-17 in San Francesco CA, giving a talk on quantum bootstrap embedding at the Quantum Computing for Tackling Challenges in Quantum Chemistry Symposium!
Jul 23, 2023 I gave a talk on quantum advantage in continuous-variable quantum sensing in the Quantum Sensing Gordon Research Seminar/Conference in Les Diablerets, Switzerland!
Apr 24, 2023 Our paper on a perturbative model for noisy quantum signal processing is published on Phys. Rev. A!
