Quantum Sensing and Quantum Optomechanics Laboratory | Purdue University

We study the quantum interaction between light and matter at atomic and nanoscales for quantum sensing and quantum information processing. In particular, we are interested in spin qubits in 2D materials, levitated optomechanics, Casimir effects, and quantum biological and chemical sensing. Our recent work on GHz rotation of an optically levitated nanoparticle was selected as one of the 10 APS Physics “Highlights of the Year” of 2018. Our research on on-chip optical levitation with a metalens was included in 30 breakthroughs in “Optics in 2022” by the Optics & Photonics News.
