We investigate the quantum walks of a single particle in one-dimensional periodically kicked circuit electrodynamics lattice. It is found that dynamic process walker affected by strength incommensurate potentials and driven periods system. calculate mean square displacement to illustrate properties walks, which shows localized presents zero power-law index distribution. By calculating information entropy, we find next-nearest-neighbor interactions have remarkable deviation effects on make more stricter parameter condition for localization walker. Moreover, assisted lattice-based cavity input-output process, features lattice can be observed measuring average photon number field steady state.
