Tensor invariants for multipartite entanglement classification
Sylvain Carrozza, Johann Chevrier, Luca Lionni
Organising the space of entanglement structures of a multipartite quantum system is a much more challenging task than its bipartite version: while the local unitary (LU) orbit of a…

Large factorization of families of tensor trace-invariants
Sylvain Carrozza, Johann Chevrier, Luca Lionni
It was recently proven that, in contrast to their matrix analogues, the moments of a real Gaussian tensor of size N do not in general factorize over their connected components in t…
