The paper reports on a high-intensity source of polarization-entangled photon pairs, which uses type-II noncollinear phase matching in parametric down conversion. This method directly produces true entanglement without the need to discard any part of the wave function, unlike previous schemes. The source achieves two-photon fringe visibilities exceeding 97%, allowing for a violation of Bell’s inequality by over 100 standard deviations in less than 5 minutes. The setup uses a BBO crystal with specific orientation and additional birefringent elements to compensate for longitudinal and transverse walk-off effects, enabling the production of all four EPR-Bell states. The source is brighter and more stable than previous methods, making it suitable for various quantum communication and information experiments, including quantum cryptography, teleportation, and quantum computation.The paper reports on a high-intensity source of polarization-entangled photon pairs, which uses type-II noncollinear phase matching in parametric down conversion.
