    "abstract": "Photon entanglement is an essential ingredient for linear optics quantum\ncomputing schemes, quantum cryptographic protocols and fundamental tests of\nquantum mechanics. Here we describe a setup that allows for the generation of\npolarisation-entangled N-photon states on demand. The photons are obtained by\nmapping the entangled state of N atoms, each of them trapped inside an optical\ncavity, onto the free radiation field. The required initial state can be\nprepared by performing postselective measurements on the collective emission\nfrom the cavities through a multiport beamsplitter.",
