Separability of Multi-Partite Quantum States

Abstract We give a direct tensor decomposition for any density matrix into Hermitian operators. Based upon the decomposition we study when the mixed states are separable and generalize the separability indicators to multi-partite states and show that a density operator is separable if and only if the separable indicator is non-negative. We then derive two bounds for the separable indicator in t...

Multi-partite quantum cryptographic protocols with noisy GHZ States

We propose a wide class of distillation schemes for multi-partite entangled states that are CSS-states. Our proposal provides not only superior efficiency, but also new insights on the connection between CSS-states and bipartite graph states. We then apply our distillation schemes to the tri-partite case for three cryptographic tasks—namely, (a) conference key agreement, (b) quantum sharing of ...

Separability of Rank Two Quantum States

Explicit sufficient and necessary conditions for separability of higher dimensional quantum systems with rank two density matrices are given. A nonseparability inequality is also presented, for the case where one of the eigenvectors corresponding to nonzero eigenvalues is a maximally entangled state. PACS numbers: 03.65.Bz, 89.70.+c 1 SFB 256; SFB 237; BiBoS; CERFIM(Locarno); Acc. Arch.; USI(Me...

Separability criterion for multipartite pure quantum states

Using the modified tensor product of graphs defined in [1], we present here a graphical criterion for the separability of m-partite pure quantum states living in a real or complex Hilbert space. The criterion gives both necessary and sufficient condition for the separability of such states. This criterion was first conjectured by S. L. Braunstein, S. Ghosh, T. Mansour, S. Severini, and R. C. Wi...

The Quantum Separability Problem for Gaussian States

The concept of entanglement arose with the question of completeness of quantum theory [1]. Nowadays entanglement is regarded as a fundamental property of certain quantum states and it appears to be an important physical resource. In some sense, entanglement is synonymous of inseparability because entangled states possess some global properties that cannot be explained in terms of only the parti...
