Platonic quantum networks as coherence-assisted switches in perfect and imperfect situations

The concept of coherence switches with nanoparticle platonic networks is introduced and analysed. The platonic networks store an initially injected excitation for extremely long durations via the formation of dark states. Switching is achieved by the nano-mechanical arrangements of one site or some part of the network to remove the trapping thus leading to a highly efficient transfer to the target which is irreversibly connected to one site. We present coherence switches based on controlling a cubic network both in the absence and presence of environment and manufacturing/topological noise.
