Relation between three-qubit entanglement invariants and two-qubit concurrence

Wen-Long Yang, Jing-Ling Chen
2007 Physical Review A. Atomic, Molecular, and Optical Physics  
In this Brief Report we show the relation between three-qubit entanglement invariants and two-qubit concurrence with the help of projective measurements. How to use these invariants to represent the entanglement property of three-qubit pure states is also investigated.
