A new quantum mechanical photon counting distribution formula
Hong-yi Fan, Hong-chun Yuan, Li-yun Hu
By virtue of density operator's P-representation in the coherent state representation, we derive a new quantum mechanical photon counting distribution formula. As its application,…
Quantum mechanical photon-count formula derived by entangled state representation
Li-yun Hu, Z. S. Wang, L. C. Kwek +1
By introducing the thermo entangled state representation, we derived four new photocount distribution formulas for a given density operator of light field. It is shown that these n…
Quantum Optical Version of Classical Optical Transformations and Beyond
Hong-yi Fan, Li-yun Hu
By the newly developed technique of integration within an ordered product (IWOP) of operators, we explore quantum optical version of classical optical transformations such as optic…
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}…
