Original Title:
Tripartite Entanglement and its transfer
Translated title:
Tripartite Entanglement and its transfer
Summary:
In this work we study the quantification of entanglement for a tripartite
quantum system and the transfer of maximally entangled tripartite states.
This problem is part of a broader active research field concerned with the
study and manipulation of entanglement of multipartite systems with many
applications in quantum information.
Specifically, we mention some important properties for the classification
of tripartite systems in terms of their entanglement. Subsequently, we consider
a newly proposed entanglement measure for tripartite systems, called
Concurrence Fill, and discuss how it compares with previously proposed entanglement
measures in the literature and highlight its advantages.
Finally, we focus on the transfer of tripartite states with maximal Concurrence
Fill in a chain of 1
2 -spins described by the Hamiltonian of the Heisenberg
model. We find that such a transfer is possible for the chain lengths we
considered and we present the characteristics of the solutions.
