Abstract: We investigate entangled states of an atomic trapped ion interacting with two phonons in the Λ configuration forming a twelve-dimensional Hilbert space. We study two elaborated measures, namely, the concurrence C and negativity N, which… read more here.

Abstract: The k-ME concurrence as a measure of multipartite entanglement (ME) unambiguously detects all k-nonseparable states in arbitrary dimensions and satisfies many important properties of an entanglement measure. Negativity is a simple computable bipartite entanglement measure.… read more here.
