Radial and Azimuthal Profiles of Two-Qubit/Rebit Hilbert-Schmidt Separability Probabilities
Radial Azimuthal Profiles Two-Qubit/Rebit Hilbert-Schmidt Separability Probabilities
2010/11/8
We reduce the long-standing problem of ascertaining the Hilbert-Schmidt probability that a generic pair of qubits is separable to that of determining the specific nature of a one-dimensional (separabi...
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...
Criteria excluding full separability of multi-qubit quantum states
Criteria excluding full separability multi-qubit quantum states
2010/10/20
We introduce a criterion to exclude full separability of quantum states. We present numerical evidence that the criterion is necessary and sufficient for the class of GHZ diagonal three-qubit states a...
The RCCN criterion of separability for states in infinite-dimensional quantum systems
The RCCN criterion of separability states infinite-dimensional quantum systems
2010/10/18
In this paper, the realignment criterion and the RCCN criterion of separability for states in infinite-dimensional bipartite quantum systems are established. Let HA and HB be complex Hilbert spaces wi...
Twopartite, combinatorial approach to partial k-separability problem for general multipartite states
k-separability problem Twopartite
2010/3/10
We describe a general methods to localize any sort of k-separability and therefore also the corresponding partial entanglement in genuinely multipartite mixed quantum states. Our methods are based exc...
