TL;DR
This paper investigates the entanglement properties of a quantum optical elliptical vortex state using Wigner functions, revealing a counterintuitive relationship between vorticity, squeezing, and entanglement.
Contribution
It introduces a method to analyze entanglement in elliptical vortex states and uncovers a critical squeezing threshold affecting entanglement levels.
Findings
Entanglement decreases with higher vorticity beyond a critical squeezing.
A critical squeezing parameter exists where entanglement behavior changes.
The study provides insights into the quantum properties of elliptical vortex states.
Abstract
We calculate the entanglement of a generalized elliptical vortex formed by quantized radiation field, using Wigner quasiprobability distribution function for such states. We find a critical squeezing parameter above which the entanglement is less for higher vorticity, which is counter intuitive.
