Quantum analysis of polarization entanglement degradation induced by multiple-photon-pair generation
R. A. Brewster, Gerald Baumgartner, Yanne K. Chembo
Abstract
The formation of multiple photon pairs in spontaneous parametric down-conversion leads to a degradation of polarization entanglement quality. The authors characterize this quality and perform all-quantum calculations that agree with known results for two different Bell-state-generation methods.
