Entanglement entropy plays an important role when one studies correlations in quantum field theory. In this talk, I discuss the relation between entanglement production of quantum systems and instabilities in their classical counterpart. In particular, I present a new theorem stating that in classically unstable linear systems the entanglement entropy grows linearly. Its slope is given by a sum over the Lyapunov exponents of the system.
