  It is widely spread in the literature that non-Markovianity (NM) may be
regarded as a resource in quantum mechanics. However, it is still unclear how
and when this alleged resource may be exploited. Here, we study the
relationship between NM and quantum optimal control under the objective of
generating entanglement within M non-interacting subsystems, each one coupled
to the same non-Markovian environment. Thus, we design a variety of entangling
protocols that are only achievable due to the existence of the environment. We
show that NM plays a crucial role in all the entangling protocols considered,
revealing that the degree of NM completely determines the success of the
entangling operation performed by the control. This is a demonstration of the
virtues of NM and the way that it can be exploited in a general entangling
setup.
