Entanglement of two qubits mediated by one-dimensional plasmonic waveguides
Entanglement two qubits mediated one-dimensional plasmonic waveguides
2010/11/11
We investigate qubit-qubit entanglement mediated by plasmons supported by one-dimensional waveguides. We explore both the situation of spontaneous formation of entanglement from an unentangled state ...
Reexamination of determinant-based separability test for two qubits
Reexamination determinant-based separability qubits
2010/10/29
It was shown in [Augusiak et al.,\;Phys. Rev. A \textbf{77}, 030301(R) (2008)] that discrimination between entanglement and separability in a two qubit state can be achieved by a measurement of a sin...
Entanglement dynamics of two qubits under the influence of external kicks and Gaussian pulses
Entanglement dynamics two qubits influence external kicks Gaussian pulses
2010/10/19
We have investigated the dynamics of entanglement between two spin-1/2 qubits that are sub-
ject to independent kick and Gaussian pulse type external magnetic elds analytically as well as numericall...
q-entropies and the entanglement dynamics of two-qubits interacting with an environment
q-Entropies Entanglement dynamics
2010/7/5
We investigate entropic aspects of the quantum entanglement dynamics of two-qubits systems interacting with an environment. In particular we consider the detection, based on the violation of classical...
