Abstract

All the dynamical limitations connected to the energy of a system in a quantum speed limit relation which establishes how fast any physical system can evolve given its energy characteristics were assembled. It was proved that homogeneous separable pure states cannot exhibit speedup, while at least one entangled case that exhibits speedup exists. Thus, a fundamental role of energy entanglement in the dynamical evolution of composite systems was given.
