Concurrence, introduced by Hill and Wootters (Phys Rev Lett 78:5022, 1997), provides an important measure of entanglement for a general pair of qubits that is faithful: strictly positive for entangled states and vanishing for all separable states. Such a measure captures the entire content of entanglement, providing necessary and sufficient conditions for separability. We present an extension of concurrence to multiparticle pure states in arbitrary dimensions by a new framework using the… 

Generalized entanglement measure for continuous-variable systems

Concurrence introduced by Hill and Wootters [Phys. Rev. Lett. 78 , 5022 (1997)], provides an important measure of entanglement for a general pair of qubits that is strictly positive for entangled

Geometric quantification of multiparty entanglement through orthogonality of vectors

The wedge product of vectors has been shown to yield the generalised entanglement measure I-concurrence, wherein the separability of the multiparty qubit system arises from the parallelism of vectors

Complete complementarity relations for multipartite pure states

By exploring the purity of bi- and tri-partite pure quantum states, it is shown that it is possible to obtain complete complementarity relations and this procedure allows us to create a general framework for obtaining complete complement parity relations for a subsystem that belongs to an arbitrary multi- partite quantum system in a pure state.

Complete complementarity relations and their Lorentz invariance

It is well known that entanglement under Lorentz boosts is highly dependent on the boost scenario in question. For single-particle states, a spin-momentum product state can be transformed into an

The three way distributive entanglement is shown to be related to the parallelism of vectors. Using a measurement based approach we form a set of 2-dimensional vectors, representing the post
