Abstract
We study transport properties of two entangled photons which are initially injected into two nearest-neighbor coupling cavities in a one-dimensional coupled-cavity array (CCA). It is found that photonic transport dynamics in the two-photon CCA exhibits entanglement-enhanced two-photon delocalization (TPD) phenomenon. It is shown that the CCA can realize the localization-to-delocalization transition for two entangled photons.
