Size invariant twisted optical modes for efficient generation of higher dimensional quantum states
Ali Anwar, Shashi Prabhakar, R. P. Singh
Optical vortex beams are profiled as helical wavefronts with a phase singularity carrying an orbital angular momentum (OAM) associated with their spatial distribution. The transver…
Polarization-orbital angular momentum duality assisted entanglement observation for indistinguishable photons
Nijil Lal, Sarika Mishra, Anju Rani +3
Duality in the entanglement of identical particles manifests that entanglement in only one variable can be revealed at a time. We demonstrate this using polarization and orbital an…
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…
Optical vortex produced by Single Photon Subtraction from two mode squeezed state Produces Maximum Entanglement
Abir Bandyopadhyay, Anindya Banerji, R. P. Singh
In this article we report that the entanglement produced by single photon subtraction is maximum, by studying the entanglement of multi photon subtraction from two mode squeezed st…
Wigner distribution function and entanglement of generalized quantum optical vortex
Abir Bandyopadhyay, Shashi Prabhakar, R. P. Singh
We calculate the Wigner (quasi)probability distribution function of the quantum optical elliptical vortex (QEV), generated by coupling squeezed vacuum states of two modes. The coup…
