Conversion of entanglement between continuous variable and qubit systems
Xiao-yu Chen, Liang-neng Wu, Li-zhen Jiang +1
We investigate how entanglement can be transferred between continuous variable and qubit systems. We find that a two-mode squeezed vacuum state and a continuous variable Werner sta…
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 condition for entanglement enhanced information transmission of Pauli memory channel
Xiao-yu Chen
The sufficient condition of entanglement enhanced classical capacity is given for Pauli memory channel with arbitrary channel parameters. In some special case the condition is also…
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…
The characteristic function of optical evolution
Xiao-yu Chen
The master equation of quantum optical density operator is transformed to the equation of characteristic function. The parametric amplification and amplitude damping as well as the…
