Generating a perfect quantum optical vortex
arXiv:1603.00321 · doi:10.1103/PhysRevA.94.053838
Abstract
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 examine its nonclassical properties using the Wigner function and the negativity volume. Such a quantum state can be a useful resource for quantum information processing and communication.
