Proposal of a transmon-based high bandwidth quantum router
Dibyendu Chatterjee, Arijit Roy
Larger bandwidth is an ever increasing demand of any communication system. Due to the unique device features, transmon is proposed to use in quantum communication. Not only as a quantum router, but transmon can also be used as quantum Josephson parametric amplifier. Josephson parametric amplifier provides high gain-bandwidth product which can be increased to a level beyond the traditional gain-bandwidth product. The larger bandwidth in Josephson parametric amplifier is achievable by appropriate impedance engineering which can be integrated to the hardware of the transmon-based router. We proposed here a quantum router with wider bandwidth and it is shown that the gain profile is very flat with a wide frequency of the quantum router.
