Generation of a CW anti-bunched photon field from a thin-film PPLN waveguide by two-photon interference with a weak coherent state
Yue Li, Haochuan Li, Yuhang Lei +7
An anti-bunched photon field is produced from a thin-film ppln waveguide by mixing the on-chip two-photon state with a weak but matched coherent state. This is achieved by taking o…

Observation of quantum noise reduction in a Raman amplifier via quantum correlation between atom and light
Jianmin Wang, Rong Zhu, Yue Li +1
Any amplifier requires coupling to its internal degrees of freedom for energy gain. This coupling introduces extra quantum noise to the output. On the other hand, if the internal d…
