Abstract: 

Narrow-band bi-photon generation from high optical depth cold atom ensemble via DLCZ(Duan-Lukin-Cirac-Zoller) procedure has become a vital topic in the research frontier of quantum optics with cold atoms. It provides a testbed for a lot of new physics, involving not only the four-wave-mixing process, but also the EIT(electromagnetically induced transparency) process. In this talk, I will report some of my previous experimental work on this topic, such as single-photon waveform modulation and multi-photon interferences. Moreover, I will also discuss my own thoughts on its potential development for the future.
