Two Photon Anti-Coalescence Interference: the Signature of Two Photon Entanglement
arXiv:quant-ph/0305074 · doi:10.1209/epl/i2003-00503-6
Abstract
We study a general theory on the interference of two-photon wavepacket in a beam splitter. We find that the symmetry of two-photon spectrum plays an important role in the manners of interference. We distinguish the coalescence and anti-coalescence interferences, and prove that the anti-coalescence interference is the signature of photon entanglement.
