Most networked systems of scientific interest are characterized by
temporal links, meaning the network’s structure changes over time. Link
temporality has been shown to hinder many dynamical processes, from
information spreading to accessibility, by disrupting network paths.
Considering the ubiquity of temporal networks in nature, we ask: Are
there any advantages of the networks’ temporality? We use an analytical
framework to show that temporal networks can, compared to their static
counterparts, reach controllability faster, demand orders of magnitude
less control energy, and have control trajectories, that are
considerably more compact than those characterizing static networks.
Thus, temporality ensures a degree of flexibility that would be
unattainable in static networks, enhancing our ability to control them.
