Coincidence free certification and quantification of spatial entanglement with stimulated parametric down conversion
M. G. Damaceno, G. H. dos Santos, N. Rubiano da Silva +2
Using stimulated emission, a photon pair source can be characterized by seeding the signal mode with a bright classical beam and measuring the stimulated idler field, thus replacin…

Twisted Gaussian Schell States in Quantum Optics: Twist-Assisted Nonclassicality and Entanglement
Fabricio Toscano, G. Cañas, A. Z. Khoury +2
We introduce the Twisted Gaussian Schell (TGS) state, a two-mode mixed Gaussian state defined as the quantum-optical analog of the Twisted Gaussian Schell-model beam of classical p…
