Azimuthal entanglement and multimode schmidt decompositions for noncollinear biphotons

2016 · Bulletin of the Russian Academy of Sciences Physics

Noncollinear biphoton states are found to possess a very high degree of azimuthal entanglement with typical values of ~10 4 for Schmidt parameter K (the ratio of the pump wavelength to its waist). A scheme …

Entanglement of multiphoton polarization Fock states and their superpositions

2018 · arXiv (Cornell University)

Density matrices of pure multiphoton Fock polarization states and of arising from them reduced density matrices of mixed states are expressed in similar ways in terms of matrices of correlators defined as averaged products of …
