ABSTRACT

The superconducting quantum computation experiment based on Josephson junction and linear resonator has made great progress in recent years, and the macroscopic regulation of linear field of harmonic oscillator has greatly expanded the scope of the original cavity quantum electrodynamics , Formed the so-called circuit quantum electrodynamics. In this paper, we combine the current direction of the field of superconducting quantum computing to expand quantum computing and circuit quantum electrodynamics research from circuit design, numerical simulation and experimental measurement. We first try to optimize the existing experimental system, through the numerical modeling and software simulation and experimental approach to optimize the quantum computing gate and optimize the circuit design parameters, thereby improving the efficiency of quantum computing. We are also committed to the study of quantum bits and linear harmonic oscillator under the strong coupling of many novel physical phenomena. For the most critical decoherence problem in superconducting quantum devices, we will investigate the effects of decoupling on the system, such as two energy levels and quasi-particle excitation, by systematic experimental measurements. This series of studies will have an important role in promoting superconducting quantum computing and quantum modeling. More... »
