Operator transpose within normal ordering and its applications for quantifying entanglement
Liyun Hu, Luping Zhang, Xiaoting Chen +3
Partial transpose is an important operation for quantifying the entanglement, here we study the (partial) transpose of any single (two-mode) operators. Using the Fock-basis expansi…
Photon blockade in a bi-mode nonlinear nano-cavity embedded with a quantum-dot
Xinyun Liang, Zhenglu Duan, Qin Guo +3
We study the interaction between a quantum-dot and a bi-mode micro/nano-optical cavity composed of second-order nonlinear materials. Compared with the Jaynes-Cummings (J-C) model,…
Conventional and unconventional photon blockade effects in an atom-cavity system
Xinyun Liang, Zhenglu Duan, Qin Guo +3
A two-level system interacting with a cavity field is an important model for investigating the photon blockade (PB) effect. Most work on this topic has been based on the assumption…
Intermediate Coherent-entangled State Representation: Generation and its applications
Qin Guo, Li-ying Jiang, Cun-jin Liu +2
By combining the beam splitter and the Fresnel transform, a protocol is proposed to generate a new entangled state representation, called the intermediate coherent-entangled state…
M Times Photon Subtraction-Addition Coherent Superposition Operated Odd-Schrődinger-cat State: Nonclassicality and Decoherence
Li Huang, Qin Guo, Li-ying Jiang +3
We introduce a new non-Gaussian state, generated by m times coherent superposition operation (MCSO) on odd-Schrodinger-cat state (OSCS). Its norm…
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…
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…
Husimi operator and Husimi function for describing electron's probability distribution in uniform magnetic field derived by virtue of the entangled state representation
Hong-yi Fan, Qin Guo
For the first time we introduce the Husimi operator Delta_h(gamma,varepsilon;kappa) for studying Husimi distribution in phase space(gamma,varepsilon) for electron's states in unifo…
