Abstract We demonstrate a new generation mechanism for polarisation- and colour-entangled photon pairs. In our approach we tailor the phase-matching of a periodically poled KTP crystal such that two downconversion processes take place simultaneously. Relying on this effect. our source emits entangled bipartite photon states. https://www.diegojavierfares.com/bargain-Merlin-the-Magical-Wizard-Boys-Costume-special-save/
