Conversion of position correlation into polarization entanglement
Chithrabhanu Perumangatt, Alexander Lohrmann, Alexander Ling · Conference on Lasers and Electro-Optics · 2019
The photon pairs generated by parametric down conversion of a laser beam have inherent position and momentum correlations. We generate polarization entangled photons by manipulating the position correlations using a modified Mach-Zehnder interferometer containing a wedge mirror. The polarization entangled photon pairs exhibit strong quantum correlations and high brightness.
