We investigate the quantum correlation and the temporal coherence of twin photons counterpropagating in periodically poled crystals, showing a peculiar transition from a high temporal entanglement to a separable state as the pump spectrum broaden

Abstract
We investigate the quantum correlation and the temporal coherence of twin photons counterpropagating in periodically poled crystals, showing a peculiar transition from a high temporal entanglement to a separable state as the pump spectrum broaden
