Query: Perfect routing of quantum information in regular cavity QED networks   We introduce a scheme for perfect routing of quantum states and entanglement
in regular cavity QED networks. The couplings between the cavities are
quasi-uniform and each cavity is doped with a two-level atom. Quasi-uniform
couplings leads the system to evolve in invariant subspaces. Combination the
evolutions of the system in its invariant subspaces with quite simple local
operations on atoms in the networks, gives the perfect routing of quantum
states and entanglement through the network. To provide the protocol be robust
due to decoherence arisen from photon loss, the field mode of the cavities are
only virtually excited.
