Polarization-entangled photon pair sources based on spontaneous four wave mixing assisted by polarization mode dispersion

Abstract Photonic-based qubits and integrated photonic circuits have enabled demonstrations of quantum information processing (QIP) that promises to transform the way in which we compute and communicate. To that end, sources of polarization-entangled photon pair states are an important enabling tech...
