| Abstract: | Narrow-band entangled photon pairs could not only provide powerful tools to test some basic concepts of quantum mechanics,e.g.,nonlocal property,but also be used to improve long-distance quantum communication and scalable distributed linear optical quantum computation.The authors reviewed the experimental aspects of the generation and modulation of such kind of narrow-band entangled photon pairs in cold atoms through spontaneous four wave mixing and electromagnetic induced transparency. |

| Keywords: | narrow-band entangled photon pairs four wave mixing cold atoms |
