Witnessing Entanglement with Second-Order Interference
arXiv:quant-ph/0408047 · doi:10.1103/PhysRevA.71.032304
Abstract
Second-order interference and Hanbury-Brown and Twiss type experiments can provide an operational framework for the construction of witness operators that can test classical and nonclassical properties of a Gaussian squeezed state (GSS), and provide entanglement witness operators to study the separability properties of correlated Gaussian squeezed sates.
