Multipixel sub-shot noise phase measurement with classical light interferometry
Mandeep Singh, Kedar Khare, Anand Kumar Jha +2
We demonstrate accurate phase measurement from low photon level interference data using a constrained optimization method that takes into account the expected redundancy in the unk…
Violation of Bell's inequality for phase singular beams
Shashi Prabhakar, Salla Gangi Reddy, A. Aadhi +3
We have considered optical beams with phase singularity and experimentally verified that these beams, although being classical, have properties of two mode entanglement in quantum…
Entanglement propagation of a quantum optical vortex state
Anindya Banerji, Ravindra Pratap Singh, Dhruba Banerjee +1
We study the entanglement evolution of a quantum optical vortex state propagating through coupled lossless waveguides. We consider states generated by coupling two squeezed modes u…
Spatial distribution of Spontaneous Parametric Down-Converted Photons for higher order Optical Vortices
Shashi Prabhakar, Salla Gangi Reddy, A Aadhi +4
We make a source of entangled photons (SEP) using spontaneous parametric down-conversion (SPDC) in a non-linear crystal and study the spatial distribution of photon pairs obtained…
