Quantum Information with Even/Odd States of Orbital Angular Momentum of Light
Chithrabhanu Perumangatt, Nijil Lal, Ali Anwar +2
We address the possibility of using even/odd states of orbital angular momentum (OAM) of photons for the quantum information tasks. Single photon qubit states and two photon entang…
Selecting the pre-detection characteristics for effective fiber coupling of entangled photon sources
Ali Anwar, Chithrabhanu P, Salla Gangi Reddy +2
Photon modes have an important role in characterizing the quantum sources of light. Proper coupling of various photon modes obtained in spontaneous parametric down conversion (SPDC…
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…
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…
