A classification of entanglement in three-qubit systems

Understand

We present a classification of three-qubit states based in their three-qubit and reduced two-qubit entanglements.

• For pure states these criteria can be easily implemented, and the different types can be related with sets of equivalence classes under Local Unitary operations.
• For mixed states characterization of full tripartite entanglement is not yet solved in general; some partial results will be presented here.
