论文摘要
状态$ g^{\ hat {n}} \ hat {a}^{†m} \ left \ welet \ vertα\ ryn \ rangle $和状态$ \ hat {a}^a}^{†m} g^{ $ \ hat {a}^{†m} \ left \ vertgα\ right \ rangle $，它被我们称为Multi-Photon-Addition放大相干状态（MPAAC）。在这里，$ \ hat {n} $，$ \ hat {a}^{†} $，$ \ left \ welet \ vertα\ right \ rangle $，$ g $（$ \ geq 1 $）和$ m $是光子数量操作员，创建者，创建者，coherent state，Coherent State，Coherent State，Facor，Facor等。我们研究这些MPAACS的数学和物理特性，包括标准化，光子组件分析，Wigner函数，有效增益，正交挤压和等效输入噪声。实际上，包含更多非古老性的MPAAC是Agrwal和Tara [Phys]引入的光子增添相干状态（PAC）的放大版本。 Rev. A 43，492（1991）]。我们的工作提供了用于实施光场放大器的理论参考。
State $g^{\hat{n}}\hat{a}^{†m}\left\vert α\right\rangle $ and state $\hat{a}^{†m}g^{\hat{n}}\left\vert α\right\rangle $ are same to state $\hat{a}^{†m}\left\vert gα\right\rangle $, which is called as multi-photon-addition amplified coherent state (MPAACS) by us. Here, $\hat{n}$, $\hat{a}^{†}$, $\left\vert α\right\rangle $, $g$ ( $\geq 1$), and $m$ are photon number operator, creation operator, coherent state, gain facor, and an interger, respectively. We study mathematical and physical properties for these MPAACSs, including normalization, photon component analysis, Wigner function, effective gain, quadrature squeezing, and equivalent input noise. Actually, the MPAACS, which contains more nonclassicality, is an amplified version of photon-added coherent state (PACS) introduced by Agrwal and Tara [Phys. Rev. A 43, 492 (1991)]. Our work provides theoretical references for implementing amplifiers for light fields.
