Abstract
We study the entanglement capability of the evolution of a pair of qubits evolving under unitary dynamics, when the local dynamical parameters cannot be modified during the time-evolution. Unlike the fast local control regime, we find that local and non-local contributions to the dynamics are strictly interconnected. Moreover, it is possible to strongly increase the entanglement capability by suitably initializing the characteristic energies of the two parties.
