Laguerre polynomial excited coherent states generated by multiphoton catalysis: Nonclassicality and Decoherence
Li-Yun Hu, Jia-Ni Wu, Zeyang Liao +1
We theoretically introduce a new kind of non-Gaussian state-----Laguerre polynomial excited coherent states by using the multiphoton catalysis which actually can be considered as a…
Improving entanglement of even entangled coherent states by a coherent superposition of photon subtraction and addition
Shi-You Liu, Jie-Hui Huang, Li-Yun Hu +3
A new entangled quantum state is introduced by applying local coherent superposition (ra^+ +ta) of photon subtraction and addition to each mode of even entangled coherent state (EE…
Separability criterion for bipartite states and its generalization to multipartite systems
Jie-Hui Huang, Li-Yun Hu, Lei Wang +1
A group of symmetric operators are introduced to carry out the separability criterion for bipartite and multipartite quantum states. Every symmetric operator, represented by a symm…
Nonclassicality and decoherence of photon-added squeezed thermal state in thermal environment
Li-Yun Hu, Zhi-Ming Zhang
Theoretical analysis is given of nonclassicality and decoherence of the field states generated by adding any number of photons to the squeezed thermal state (STS). Based on the fac…
Comments on "Asking Photons Where They Have Been"
Jie-Hui Huang, Li-Yun Hu, Xue-Xiang Xu +4
By using the nonuniform discrete Fourier transform on the center positions of the symmetric intensity distribution of the output beam, we recover the vibration information of two m…
Nonclassical properties of Hermite polynomial's excitation on squeezed vacuum and its decoherence in phase-sensitive reservoirs
Shi-You Liu, Ya-Zhou Li, Li-Yun Hu +3
We introduce Hermite polynomial excitation squeezed vacuum (SV) H_{n}(O)S(r)|0> with O=u a+v a^{+}. We investigate analytically the nonclassical properties according to Mandel's Q…
