protocols is the type of correlation that is utilized, which could be intensity correlation, amplitude correlation or time-frequency correlation, etc.\
The most important component of correlation enhanced target detection protocols is the non-classical light sources. There has been astounding progress in the prowess of such non-classical sources in the last decade [@Kang:2016; @Kang:2015]. In particular, it has been shown that integrated monolithic semiconductor devices can be used to generate and tailor high-quality quantum states of light in active semiconductor structures, such as aluminum gallium arsenide (AlGaAs) devices [@Valles:2013; @Horn:2012]. Such structures can directly produce non-classical twin beams without any additional off-chip interferometry, spectral filtering, compensation, or post-selection. The generated twin beams could be effectively coupled into optical fiber or integrated target detection systems. The flexibility in waveguide structure design also allows for efficient dispersion control and quantum state engineering.\
In this article, we provide a review of the recent advances in optical target detection that exploit the strong temporal correlation of non-classical twin beams [@liu2019enhancing; @trans]. We theoretically analyze and experimentally demonstrate a prototype target detection protocol with a semiconductor waveguide source. The experimental result shows substantial enhancement of the target detection performance as compared to the classical protocol that
