Optical ranging with quantum advantage
Sankar Davuluri, Greeshma Gopinath, Matt J. Woolley
The quantum illumination technique requires joint measurement between the idler and the probe reflected from the low-reflective target present in a noisy environment. The joint mea…

Continuous variable entanglement between propagating optical modes using optomechanics
Greeshma Gopinath, Yong Li, Sankar Davuluri
This article proposes a new method to entangle two spatially separated output laser fields from an optomechanical cavity with a membrane in the middle. The radiation pressure force…
