Qi-Yu Liang

Qi-Yu (Grace) Liang is an Assistant Professor in the Department of Physics and Astronomy at Purdue University. Her research focuses on quantum information transfer, quantum optics, and sensing using Rydberg atoms. She holds a Ph.D. from MIT (2017) and a B.S. from Peking University (2009). Her group explores programmable quantum transport in Rydberg atom arrays, electric field control for precision experiments, and applications of Rydberg interactions in quantum sensing.

Education:

• Ph.D. in Physics, Massachusetts Institute of Technology, 2017
• B.S. in Physics, Peking University, 2009

Research Interests:

• Quantum hardware development for scalable information processing
• Rydberg atom arrays for entanglement distribution and sensing
• Electric field control techniques for sub-wavelength atomic systems
• Topological features in spin-orbit coupled quantum gases
• Quantum nonlinear optics at the single-photon level

Lab Activities: The Liang group operates in PHYS B76 laboratory, focusing on experiments involving cold atoms and Rydberg physics. They collaborate on initiatives like the Midwest Cold Atom Workshop and organize annual Quantum Open Houses. Recent projects include developing ultra-low noise current sources for precision measurements and exploring antiblockade effects in Rydberg excitations.

Advising & Collaboration: Supervises graduate and undergraduate researchers including Yupeng Wang, Junjie Wang, and Aishik Panja. Engages in outreach activities such as hosting high school students and organizing seminars. Active in Purdue's AMO-QIS (Atomic, Molecular, and Optical - Quantum Information Science) community.
