Concurrence for general multipartite states

Published Nov 21, 2006• 6 citations

Abstract

We construct a generalized concurrence for general multipartite states based on local W-class and GHZ-class operators. We explicitly construct the corresponding concurrence for three-partite states. The construction of the concurrence is interesting since it is based on local operators and therefore gives some hints on the classification of multipartite states.

Concurrence classes for general pure multipartite states

Hoshang Heydari

We propose concurrence classes for general pure multipartite states based on an orthogonal complement of a positive operator-valued measure on quantum phase. In particular, we construct W m class, GHZ m , and GHZ m −1 class concurrences for general pure m -partite states. We give explicit expressions for W 3 and GHZ 3 class concurrences for general pure three-partite states and for W 4 , GHZ 4 and GHZ 3 class concurrences for general pure four-partite states.

Concurrence classes for a general multipartite state

Hoshang Heydari

In this paper, we will define concurrence classes for a general multipartite state based on an orthogonal complement of a positive operator valued measure on quantum phase. In particular, we will define concurrence for an arbitrary bipartite state and concurrence classes for the three- and four-partite states. And finally, we will define concurrence for $W^{m}$ and $GHZ^{m}$ classes of a general multipartite state.

DIFFERENT CLASSES OF QUANTUM GATES ENTANGLERS FOR MULTIPARTITE STATES

Hoshang Heydari

We construct quantum gates entanglers for different classes of multipartite states. In particular, we construct entangler operators for W and GHZ classes of multipartite states based on the construction of the concurrence classes. We also discuss in detail these two classes of the quantum gates entanglers for three-partite states.

Generalized GHZ-class and W-class concurrence and entanglement vectors of the multipartite systems consisting of qubits

An Min Wang

We propose two classes of the generalized concurrence vectors of the multipartite systems consisting of qubits. Making use of them, we are able to, respectively, describe and quantify GHZ-class and W-class entanglement both in total and between arbitrary two partite in the multipartite system consisting of qubits. In the case of pure state of three qubits that one partite is separable, it is shown to exactly back to the usual Wootters' concurrence after introduce a whole concurrence vector. In principle, our method is applicable to any $N$-partite systems consisting of $N$ qubits.

Minimal entanglement generating set for general pure multipartite states

Hoshang Heydari

We propose a minimal entanglement generating set for a general multipartite state based on concurrences classes. In particular, we construct concurrence for general three-partite states based on a redefinition of our concurrence classes. This shows that a measure of entanglement for three-partite states can be decomposed into two different classes that are constructed by two different local operators. Then based on this construction we introduce the minimal entanglement generating set for three-partite states. Moreover, we generalize our result to general multipartite states.
