Query: Quantum entanglement and wedge product   In this paper, I will derive a measure of entanglement that coincides with
the generalized concurrence for a general pure bi-and three-partite state based
on wedge product. I will show that a further generalization of this idea to a
general pure multipartite state with more than three subsystems will fail to
quantify entanglement, but it defines the set of separable state for such
composite state.
