When two point sources of light are close together, we just see one blurry patch. This project aims to use coherent measurement techniques in quantum optics to measure the separation between the point sources beyond the Rayleigh's limit.

Precise Earth gratitational field measurements with laser-ranging interferometry.

This project explores the nonlinear optical properties of ultrathin 2D crystals to develop highly entangled photon sources.

This project aims to be the first in the world to use radiation pressure force of laser beams to levitate a macroscopic mirror. The coherence of this resonantly amplified scheme creates a unique opto-mechanical environment for precision quantum metrology and tests of new physics theories.
