Quantum entanglement

We propose a measure of entanglement that can be computed for any pure state of an M-qubit system. The entanglement measure has the form of a distance that we derive from an adapted ap- plication of the Fubini-Study metric. This measure is invariant under local unitary transformations and defined as trace of a suitable metric that we derive, the entanglement metric g ̃. Furthermore, the analysis of the eigenvalues of g ̃ gives information about the robustness of entanglement.
