We propose a symmetrization procedure to beat decoherence for oscillator-assisted quantum gate operations. The enacted symmetry is related to the global geometric features of qubits transformation based on ancillary oscillator modes, e.g., phonons in an ion-trap system. It is shown that the devised multicircuit symmetrized evolution endows the system with a twofold resilience against decoherence: insensitivity to thermal fluctuations and quantum dissipation.
