Resumen:
We report a scheme for generation of high-order quadrature vortex states using two-modephoton-number squeezed states, generated via the non-linear process of Spontaneous ParametricDown Conversion. By applying a parametric rotation in the quadratures, using a mode converter, the Gaussian profile of the photon-number squeezed input state can be mapped into asuperposition of Laguerre-Gauss modes in the quadratures with N vortices or singularities, for aninput state containing 2N photons, thus mapping photon-number fluctuations to interference effectsin the quadratures. Our scheme has the potential to improve measurement sensitivity beyond theStandard uantum Limit, by exploiting the advantages of optical vortices, such ashigh dimensionality or topological properties, for applications requiring reduced uncertainty, suchas quantum cryptography, quantum metrology and sensing.
