Geometric quantification of multiparty entanglement through orthogonality of vectors
Abhinash Kumar Roy, Nitish Kumar Chandra, S Nibedita Swain +1
The wedge product of vectors has been shown to yield the generalised entanglement measure I-concurrence, wherein the separability of the multiparty qubit system arises from the par…
