%0 Journal Article %T Two-color ghost interference with photon pairs generated in hot atoms %A Dong-Sheng Ding %A Zhi-Yuan Zhou %A Bao-Sen Shi %A Xu-Bo Zou %J AIP Advances %D 2012 %I AIP Publishing LLC %R 10.1063/1.4754857 %X We report on an experimental observation of a two-photon ghost interference experiment. A distinguishing feature of our experiment is that the photons are generated via a non-degenerated spontaneous four-wave mixing process in a hot atomic ensemble; therefore the photon has narrow bandwidth. Besides, there is a large difference in frequency between two photons in a pair. Our works may be important to achieve more secure, large transmission capacity long-distance quantum communication. %U http://link.aip.org/link/doi/10.1063/1.4754857
