Higher order quantum vortex
Anindya Banerji, Ravindra P. Singh, Abir Bandyopadhyay
In this article we present a quantum theoretical framework of photons entangled in higher order modes like Ince-Gauss modes. Ince-Gauss modes are the natural solution of the quantu…
Generating a perfect quantum optical vortex
Anindya Banerji, Ravindra Pratap Singh, Dhruba Banerjee +1
In this article we introduce a novel quantum state, the perfect quantum optical vortex state which exhibits a highly localised distribution along a ring in the quadrature space. We…
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…
Entanglement measure using Wigner function: case of generalized vortex state formed by multiphoton subtraction
Anindya Banerji, Ravindra P. Singh, Abir Bandyopadhyay
The negativity of the Wigner function is discussed as a measure of the non classicality and the quantum interference pattern obtained therein as a possible measure of the entanglem…
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…
Quadrature Uncertainty and Information Entropy of Quantum Elliptical Vortex States
Anindya Banerji, Prasanta K. Panigrahi, Ravindra Pratap Singh +2
We study the quadrature uncertainty of the quantum elliptical vortex state using the associated Wigner function. Deviations from the minimum uncertainty states were observed due to…
