Loss-insensitive quantum noise reduction in a Raman amplifier with coherent feedback
Jianmin Wang, Rong Zhu, Z. Y. Ou
A quantum amplifier usually adds extra noise inevitably through coupling to internal degrees of freedom while amplifying the signal. The introduction of quantum correlations can ef…

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…

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…
