A Necessary and Sufficient Condition for Entanglement Witness

Published Apr 26, 2012• 0 citations

Abstract

In this paper we introduce a criterion for the characterization of Entanglement Witness for multipartite quantum systems. Our approach is based on the characterization of the "tangent space" to the set of pure product states.

Structure of Multidimensional Entanglement in Multipartite Systems

Marcus Huber, Julio I. de Vicente

We explore the structure of multipartite quantum systems which are entangled in multiple degrees of freedom. We find necessary and sufficient conditions for the characterization of tripartite systems and necessary conditions for any number of parties. Furthermore we develop a framework of multilevel witnesses for efficient discrimination and quantification of multidimensional entanglement that is applicable for an arbitrary number of systems and dimensions.

Separable Multipartite Mixed States: Operational Asymptotically Necessary and Sufficient Conditions

Fernando G. S. L. Brandão, Reinaldo O. Vianna

We introduce an operational procedure to determine, with arbitrary probability and accuracy, optimal entanglement witnesses for every multipartite entangled state. This method provides an operational criterion for separability which is asymptotically necessary and sufficient. Our results are also generalized to detect all different types of multipartite entanglement.

A necessary and sufficient criterion of separability for multipartite quantum states

Shengjun Wu, Yongde Zhang

We present a necessary and sufficient criterion for the separability of multipartite quantum states, this criterion also tell us how to write a separable multipartite state as a convex sum of separable pure states. To work out this criterion, we need to solve a set of equations, it is easy to solve these quations analytically if the density matrix of the given quantum state has few nonzero eigenvalues.

Degrees of entanglement for multipartite systems

A. I. Solomon, C.-L. Ho, Gérard Duchamp

We propose a unified mathematical scheme, based on a classical tensor isomorphism, for characterizing entanglement that works for pure states of multipartite systems of any number of particles. The degree of entanglement is indicated by a set of absolute values of the determinants for each subspace of the multipartite systems. Our scheme provides a characterization of the degrees of entanglement when the qubits are measured or lost successively, and leads naturally to necessary and sufficient conditions for multipartite pure states to be separable. For systems with a large number of particles, a rougher indication of the degree of entanglement is provided by the set of mean values of the determinantal values for each subspace of the multipartite systems.

Efficient entanglement criteria for discrete, continuous, and hybrid variables

Manuel Gessner, Luca Pezzè, Augusto Smerzi

We develop a method to construct entanglement criteria for arbitrary multipartite systems of discrete or continuous variables and hybrid combinations of both. While any set of local operators generates a sufficient condition for entanglement of arbitrary quantum states, a suitable set leads to a necessary and sufficient criterion for pure states. The criteria are readily implementable with existing technology and reveal entanglement that remains undetected by the respective state-of-the-art methods for discrete and continuous variables.

Entanglement witnesses for indistinguishable particles

A. Reusch, Jan Sperling, W. Vogel

We study the problem of witnessing entanglement among indistinguishable particles. For this purpose, we derive a set of equations which results in necessary and sufficient conditions for probing multipartite entanglement between arbitrary systems of bosons or fermions. The solution of these equations yields the construction of optimal entanglement witnesses for partial and full entanglement in discrete and continuous variable systems. Our approach unifies the verification of entanglement for distinguishable and indistinguishable particles. We provide general solutions for certain observables to study quantum entanglement in systems with different quantum statistics in noisy environments.
