Here, we demonstrate a Hamiltonian based quantum router on a four-qubit system using the IBM quantum experience platform. Transfer of information through message qubit to the desired output qubit in a router is performed by following a certain condition. Using quantum state tomography, we show that message from the input qubit gets transferred to a particular output qubit with 0.99 fidelity. Our study also presents the time evolution of the system Hamiltonian for a four-qubit quantum router. Finally, with a three output qubit router example, we illustrate the scalability of the quantum router system using the Hamiltonian required.
