  The transfer of energy through a network of nodes is fundamental to both how
nature and current technology operates. Traditionally we think of the nodes in
a network being coupled to channels that connect them and then energy is passed
from node to channel to node until it reaches its targeted site. Here we
introduce an alternate approach to this where our channels are replaced by
collective environments (or actually reservoirs) which interact with pairs of
nodes. We show how energy initially located at a specific node can arrive at a
target node - even though that environment may be at zero temperate. Further we
show that such a migration occurs on much faster time scales than the damping
rate associated with a single spin coupled to the reservoir. Our approach shows
the power of being able to tailor both the system & environment and the
symmetries associated with them to provide new directions for future quantum
technologies.
