    "abstract": "Linear optics quantum logic gates are the best tool to generate multi-photon\nentanglement. Simplifying a recent approach [Phys. Rev. A 65, 062324; Phys.\nRev. A 66, 024308] we were able to implement the conditional phase gate with\nonly one second order interference at a polarization dependent beam splitter,\nthereby significantly increasing its stability. The improved quality of the\ngate is evaluated by analysing its entangling capability and by performing full\nprocess tomography. The achieved results ensure that this device is well suited\nfor implementation in various multi photon quantum information protocols.",
