Quantum Sensing and Optomechanics Laboratory | Purdue University

We investigate quantum interactions at the atomic and nanoscale to advance quantum sensing and quantum information technologies. Our research spans spin qubits in 2D materials, levitated optomechanics, Casimir effects, and quantum sensing for chemical and biological systems. Recently, we achieved single nuclear spin detection and control in a 2D van der Waals material [Nature 643, 943 (2025)]. Our earlier work on GHz rotation of an optically levitated nanoparticle was featured among the ten “Highlights of the Year” (2018) by the American Physical Society’s Physics magazine, and our on-chip optical levitation with a metalens was recognized as one of the 30 breakthroughs in “Optics in 2022” by Optics & Photonics News.
