    "abstract": "We study a general theory on the interference of two-photon wavepacket in a\nbeam splitter. We find that the symmetry of two-photon spectrum plays an\nimportant role in the manners of interference. We distinguish the coalescence\nand anti-coalescence interferences, and prove that the anti-coalescence\ninterference is the signature of photon entanglement.",
