The entanglement of some non-two-colorable graph states
Xiao-yu Chen, Li-zhen Jiang
We exactly evaluate the entanglement of a six vertex and a nine vertex graph states which correspond to non ''two-colorable'' graphs. The upper bound of entanglement for five verti…
Quantum state conversion between continuous variable and qubits systems
Xiao-yu Chen, Liang Han, Li-zhen Jiang
We investigate how quantum state can be converted between continuous variable and qubits systems. Non-linear Jaynes-Cumings interaction Hamiltonian is introduced to accomplish the…
Simultaneous amplification and non-symmetric amplitude damping of two-mode Gaussian state
Xiao-yu Chen, Li-zhen Jiang, Ji-wu Chen
The evolution of two-mode Gaussian state under symmetric amplification, non-symmetric damping and thermal noise is studied. The time dependent solution of the state characteristic…
The entanglement of damped noon-state and its performance in phase measurement
Xiao-Yu Chen, Li-zhen Jiang, Liang Han
The state evolution of the initial optical \textit{noon} state is investigated. The residue entanglement of the state is calculated after it is damped by amplitude and phase dampin…
Relative entropy of entanglement of a kind of two qubit entangled states
Xiao-yu Chen, Li-min Meng, Li-zhen Jiang +1
We in this paper strictly prove that some block diagonalizable two qubit entangled state with six none zero elements reaches its quantum relative entropy entanglement by the a sepa…
