Rotational states in deformed nuclei: An analytic approach
deformed nuclei analytic approach
2011/7/20
The consequences of the spontaneous breaking of rotational symmetry are investigated in a field theory model for deformed nuclei, based on simple separable interactions.
Correlation and Entanglement of Multipartite States
Correlation Entanglement Multipartite States
2010/11/8
We derive a classification and a measure of classical- and quantum-correlation of multipartite qubit, qutrit, and in general, $n$-level systems, in terms of SU$(n)$ representations of density matrice...
We give a construction for a self-test for any connected graph state. In other words, for each connected graph state we give a set of non-local correlations that can only be achieved (quantumly) by th...

We prove that the family of embezzlement states defined by van Dam and Hayden[26]

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...

Continuous variable Non-Gaussian Mixed States
2010/3/10
Many different quantum information communication protocols such as teleportation, dense coding and entanglement based quantum key distribution are based on the faithful transmission of entanglement be...
Based on the mutually unbiased measurements, an optimal tomographic scheme for the single-qutrit states and two-qutrit states is presented explicitly. Because the mutually-unbiased-bases based state r...

2010/3/10
We investigate the relationship between multipartite entanglement and symmetry, focusing on permutation symmetric states. We use the Majorana representation, where these states correspond to points on...

We extend the matrix decomposition method(MDM) in classifying the $2\times N\times N$ truly entangled states to $2\times M\times N$ system under the condition of stochastic local operations and classi...

2010/10/15
A sufficient condition for a state | i to minimize the Robertson-Schr¨odinger uncertainty relation for two observables A and B is obtained which for A with no discrete spectrum is also a necessary one...

Nonlinear extensions of the two-mode squeezed vacuum states (NTMSVS's) are constructed and special cases of these states are discussed. We have constructed the NTMSVS's realization of SU(1,1) Lie alge...
