Superconducting Quantum Annealing Architecture with LC Resonators

We report on the architecture and experimental results of superconducting quantum annealer with LC resonator. In the architecture, qubit and a LC resonator are connected via a Josephson junction to realize deep strong-coupling. Such arrangement of deep strongly coupled circuit QED system is resulted with an extremely long novel quantum system. With the exceedingly gigantic compound qubit, we can realize a unique network of fully coupled large number of spins. For the actual fabrication of the system, we can conveniently separate the fabrication processes of qubit itself and resonator network. Where qubits can be fabricated by the standard Al angled evaporation, the resonator network can be fabricated by the standard Nb superconducting multilayer integration technology.
