Separability of Tripartite Quantum Systems
i pi = 1. Many separability criteria have been found in recent years. For pure states, the problem is completely solved, e.g., by using the Schmidt decomposition [1]. For mixed states, there are separability criteria such as PPT, reduction, majorization, realignment etc. [2, 3, 4, 5, 6]. In [7] the authors have given a lower bound of concurrence for tripartite quantum states which can be used t...
متن کاملSeparability and distillability of multiparticle quantum systems
Entanglement is an essential ingredient in most applications of Quantum Information. It arises when the state of a multiparticle system is non–separable; that is, when it cannot be prepared locally by acting on the particles individually. Although in recent years there have been important steps towards the understanding of this feature of Quantum Mechanics, we do not know yet how to classify an...
متن کاملSeparability criterion for separate quantum systems
Entanglement, or quantum inseparability, is a crucial resource in quantum information applications, and therefore the experimental generation of separated yet entangled systems is of paramount importance. Experimental demonstrations of inseparability with light are not uncommon, but such demonstrations in physically well-separated massive systems, such as distinct gases of atoms, are new and pr...
متن کاملFull separability criterion for tripartite quantum systems
In this paper, an intuitive approach is employed to generalize the full separability criterion of tripartite quantum states of qubits to the higher-dimensional systems (Phys. Rev. A 72, 022333 (2005)). A distinct characteristic of the present generalization is that less restrictive conditions are needed to characterize the properties of full separability. Furthermore, the formulation for pure s...
متن کاملSimulation of n-qubit quantum systems. II. Separability and entanglement
Studies on the entanglement of n-qubit quantum systems have attracted a lot of interest during recent years. Despite the central role of entanglement in quantum information theory, however, there are still a number of open problems in the theoretical characterization of entangled systems that make symbolic and numerical simulation on n-qubit quantum registers indispensable for present-day resea...
