Classification of four qubit states and their stabilisers under SLOCC operations

Heiko Dietrich, Willem A. de Graaf, Alessio Marrani +1

We classify four qubit states under SLOCC operations, that is, we classify the orbits of the group $\mathrm{SL}(2,\mathbb{C}{)}^4$ on the Hilbert space $\mathcal{H}_4 = (\ma…
