About me

I am an HQI (Harvard Quantum Initiative) Postdoctoral Fellow at Harvard University, hosted by Professor Marko Loncar.

I graduated from Purdue University with a Ph.D. degree in Physics in August 2022, supervised by Professor Tongcang Li.

My research interests focus on optomechanics, spin qubits, and quantum devices.

Ph.D., Department of Physics and Astronomy, Purdue University, August 2016-August 2022

Bachelor of Science, University of Science and Technology of China, August 2012-June 2016

Research Assistant, June 2018-August 2022

Department of Physics and Astronomy, Purdue University

§ Project: Quantum optomechanics with virtual photons (Casimir effect)

· Built a vacuum dual-cantilever atomic force microscope (AFM)

· Achieved precision measurement of Casimir force at separations ranging from 50 nm to 1000 nm

· Realized non-reciprocal energy transfer through Casimir interaction between two cantilevers

· Proposed schemes to detect Casimir torque and vacuum friction with a levitated nanoparticle

· Published in Nature Nanotechnology (2021), Physical Review A (2017), Nanophotonics (2021)

§ Project: Precision measurement by levitated optomechanics

· Created the world’s fastest nanorotor that rotates beyond 300 billion rpm

· Realized the world’s most sensitive torque detector with an optically levitated nanorotor

· Published in Nature Nanotechnology (2020), Physical Review Letters (2018) (APS “Highlights of the Year” of 2018)

§ Project: Quantum information and network by quantum emitters

· Proposed to realize the scalable network with closely-spaced diamond color centers

· Observed stable single-photon emissions from boron nitride nanotubes experimentally

· Observed plasmonic-enhanced shallow spin defects in hexagonal boron nitride experimentally

· Published in Optics Letters (2018), Optical Materials Express (2019), Nano Letters (2021)
