Reduction criterion for separability
We introduce a separability criterion based on the positive map #:$ ̃(Tr $)!$ , where $ is a trace-class Hermitian operator. Any separable state is mapped by the tensor product of # and the identity into a nonnegative operator, which provides a simple necessary condition for separability. This condition is generally not sufficient because it is vulnerable to the dilution of entanglement. In the ...
متن کاملSeparability Criterion for Density Matrices.
A quantum system consisting of two subsystems is separable if its density matrix can be written as ρ = ∑ A wA ρ ′ A ⊗ ρ ′′ A, where ρ ′ A and ρ ′′ A are density matrices for the two subsytems. In this Letter, it is shown that a necessary condition for separability is that a matrix, obtained by partial transposition of ρ, has only non-negative eigenvalues. This criterion is stronger than the Bel...
متن کاملSeparability conditions from entropic uncertainty relations
Separability is the property that distinguishes statistical ensembles that have a classical description from the ones that need a quantum description. As a matter of fact, the definition of entanglement is the formal negation of the separability condition [1]. In spite of this clear logical distinction between separable and entangled states, the borderline between these two sets is very difficu...
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 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...
