Polynomial invariants and Bell inequalities as entanglement measure of 4-qubit states

Jochen Endrejat, Helmut Buettner

We compare the polynomial invariants for four qubits introduced by Luque and Thibon, PRA {\bf 67}, 042303 (2003), with optimized Bell inequalities and a combination of two qubit co…
