To suppress decoherence of solid-state qubits which are coupled to thenon-Markovian noises, we propose a strategy to couple the qubit with a chaoticdevice, of which the broad power distribution in the high-frequency domain canbe used to freeze the noises just like the dynamical decoupling control (DDC)method. Compared with the DDC, high-frequency components can be generated bythe chaotic device even driven by a low-frequency field and we do not need tooptimize the control fields to generate complex control pulses. As anapplication to superconducting circuits, we find that various noises in a widefrequency domain, including low-frequency $1/f$, high-frequency Ohmic,sub-Ohmic, and super-Ohmic noises, can be efficiently suppressed by couplingthe qubit to a Duffing oscillator, and the decoherence rate of the qubit isefficiently decreased for about 100 times in magnitude.
