Super-resolving quantum LADAR with odd coherent superposition states sources at shot noise limit

A super-resolving quantum LADAR scheme based on odd coherent superposition states of light was studied. According to the theory of quantum optics, the output signal of traditional intensity detection, projection measurement and parity detection schemes were widely investigated and analyzed. Based on above analysis, the parity photon number resolved scheme was especially investigated. Meanwhile, the numerical results show two super-resolving features, i.e., multiple narrow peaks and well-define narrow peaks. Finally, the lowdown of the first super-resolving power of the odd coherent superposition states were analyzed and discussed in detail.
