The elaborated approach to suppressing the low-frequency decoherence by motion of the Bell states in superconducting qubit arrays is considering in this paper. This approach combines the spin-echo and motion-induced suppression of low-frequency decoherence and therefore produces a stronger tool against the low-frequency noise than is provided by the two approaches separately. The combination of the motion-induced suppression of decoherence and more complicated dynamic decoupling schemes, like Carr-Purcell pulse sequence for moving individual logical qubits, is also discussed in this paper.
