The local spectra of quantum states in SLOCC classes of n qubit states
give rise to polytopes in n-dimensional real space. While for more than
three qubits there are infinitely SLOCC classes, there are always
finitely many so-called entanglement polytopes. The entanglement
polytopes can be computed from a generating set of all covariants with
respect to the group of local transformations. Furthermore, a duality
between entanglement polytopes and algebraic varieties yields a
description of different types of entanglement. In the talk, we will
illustrate this approach and present results for entanglement polytopes
for some five qubit states.
