Schmidt-decomposition formalism is proposed to be used for evaluation of the degree of quadrature entanglement in two-mode multiphoton states. A series of examples are considered, including analysis of the quadrature entanglement of the two-mode squeezed vacuum. Single-mode and two-mode coherent states with stochastic phases are analyzed by the same method though in this case features of quadrature states are interpreted in terms of decoherence rather than entanglement.

Entanglement of multiphoton states in polarization and quadrature variables

A brief overview of entanglement characterization is given in the cases of biphoton and multiphoton polarization states. The importance of the approach is stressed based on the Schmidt decomposition.

Entanglement of multiphoton two-mode polarization Fock states and of their superpositions

Density matrices of pure multiphoton Fock polarization states and their resultant reduced density matrices of mixed states are expressed in similar ways in terms of matrices of correlators, defined

Quantum entanglement and squeezing of the quadrature difference of bright light fields

In this paper we present a scheme in which the amplitude-quadrature difference and phase-quadrature difference of two bright nonclassical beams serve as a pair of observed complementary variables

Schmidt modes and entanglement

Motivated by their frequent use in quantum mechanical studies of entanglement, we give a brief overview of Schmidt modes and Schmidt decompositions of two-particle wave functions. We discuss methods

Analysis and interpretation of high transverse entanglement in optical parametric down conversion.

TLDR
It is shown that in the monochromatic limit high values of entanglement are closely controlled by a single parameter resulting from the competition between (transverse) momentum conservation and longitudinal phase matching.

Angular Schmidt Modes in Spontaneous Parametric Down-Conversion

We report a proof-of-principle experiment demonstrating that appropriately chosen set of HermiteGaussian modes constitutes a Schmidt decomposition for transverse momentum states of biphotons

Azimuthal entanglement and multichannel Schmidt-type decomposition of noncollinear biphotons

Purely azimuthal entanglement is analyzed for noncollinear frequency-degenerate biphoton states. The degree of azimuthal entanglement is found to be very high, with the Schmidt parameter $K$ on the

TLDR
Theentanglement is presented on a diagram of the average sideband photon number required to generate the entanglement versus the average number of excess sideband photons, as deduced from the measured values of the quadrature variances.
