    "abstract": "Entanglement is at the heart of fundamental tests of quantum mechanics like\ntests of Bell-inequalities and, as discovered lately, of quantum computation\nand communication. Their technological advance made entangled photons play an\noutstanding role in entanglement physics. We give a generalized concept of\nqubit entanglement and review the state of the art of photonic experiments.",
