Information-theoretic aspects of quantum inseparability of mixed states
نویسنده
چکیده
Information-theoretic aspects of quantum inseparability of mixed states are investigated in terms of the α-entropy inequalities and teleportation fidelity. Inseparability of mixed states is defined and a complete characterization of the inseparable 2 × 2 systems with maximally disordered subsystems is presented within the Hilbert-Schmidt space formalism. A connection between teleportation and negative conditional α-entropy is also emphasized. Pacs Numbers: 03.65.Bz Typeset using REVTEX 1

Separability of mixed states: necessary and sufficient conditions
We provide necessary and sufficient conditions for the separability of mixed states. As a result we obtain a simple criterion of the separability for 2 x 2 and 2 x 3 systems. Here, the positivity of the partial transposition of a state is necessary and sufficient for its separability. However, this is not the case in general. Some examples of mixtures which demonstrate the utility of the criter...
متن کاملCharacterizing the entanglement of bipartite quantum systems
Entangled states have been known almost from the very beginning of quantum mechanics @1,2#, and their somewhat unusual features have been investigated for many years. However, recent developments in the theory of quantum information @3# have required a deeper knowledge of their properties. The simplest system where one can study entanglement is represented by a bipartite system. In such a syste...
متن کاملDecoherence effects on quantum Fisher information of multi-qubit W states
Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate t...
متن کاملFree Entanglement Measure of Multiparticle Quantum States
In this paper, based on the classfication of multiparticle states and the original definition of semiseparability , we give out the redefinition of semiseparability and inseparability of multiparticle states. By virtue of the redefinition, entanglement measure of multiparticle states can be converted into bipartite entanglement measure in arbitrary dimension in mathematical method. A simple exp...
متن کاملA quantum-information theoretic analysis of three-flavor neutrino oscillations
Correlations exhibited by neutrino oscillations are studied via quantum-information theoretic quantities. We show that the strongest type of entanglement, genuine multipartite entanglement, is persistent in the flavor changing states. We prove the existence of Bell-type nonlocal features, in both its absolute and genuine avatars. Finally, we show that a measure of nonclassicality, dissension, w...
