Résumé : What makes a quantum evolution complex? Can this complexity be characterized by (entanglement) Entropy? We argue that entropy is not just a number but there is a complexity of entanglement arising from a quantum evolution. Quantum complexity is connected to scrambling and the thermal behavior of black holes. We show that entanglement complexity is connected to the impossibility of realizing a unitary entropy pump (i.e., a freezer). We also study the transitions in complexity due to the doping of a quantum circuit by universal gates and show that the transition to complex entanglement can be obtained by just a single gate. Finally, we present a toy model for the realization of the fast scrambling conjecture as a model for a black hole.
