We study the routing of quantum information in qubit chains. This task is achieved by suitably chosen time-dependent local fields acting on the qubits. Employing the physics of coherent destruction of tunneling, we demonstrate that a driving-induced renormalization of the coupling between neighboring qubits provides the key for controlling the transduction of quantum information between permanently coupled qubits. We employ this idea for building a quantum router. Moreover, we discuss the experimental implementation with Penning traps, and study the robustness of our protocol under realistic experimental conditions, such as fabrication uncertainties and decoherence.
