Fractional Hadamard transform with continuous variables in the context of quantum optics
Li-yun Hu, Xue-xiang Xu, Shan-jun Ma
We introduce the quantum fractional Hadamard transform with continuous variables. It is found that the corresponding quantum fractional Hadamard operator can be decomposed into a s…
Wigner function evolution in self-Kerr Medium derived by Entangled state representation
Li-yun Hu, Zheng-lu Duan, Xue-xiang Xu +1
By introducing the thermo entangled state representation, we convert the calculation of Wigner function (WF) of density operator to an overlap between "two pure" states in a two-mo…
New 3-mode squeezing operator and squeezed vacuum state in 3-wave mixing
Xue-xiang Xu, Hong-yi Fan, Li-yun Hu +1
In a 3-wave mixing process occurring in some nonlinear optical medium when }{\small mode interacts with both }{\small mode and }$a_{3}^{\dagger}…
Photon-subtracted squeezed thermal state: nonclassicality and decoherence
Li-yun Hu, Xue-xiang Xu, Zi-sheng Wang +1
{\small We investigate nonclassical properties of the field states generated by subtracting any number photon from the squeezed thermal state (STS). It is found that the normalizat…
Entanglement and nonlocality of one- and two-mode combination squeezed state
Li-yun Hu, Xue-xiang Xu, Qin Guo +1
We investigate the entanglement and nonlocality properties of one- and two-mode combination squeezed vacuum state (OTCSS, with two-parameter lamda and gamma) by analyzing the logar…
