A combination of dynamical decoupling, zero noise extrapolation, and Pauli twirling now restores reliable operation within adaptive variational algorithms where depolarizing noise previously caused failure. Earlier attempts at improving resilience, using TETRIS layering, proved effective against amplitude or phase damping but lacked broad applicability. This work pinpoints vulnerabilities during operator selection, opening new avenues for practical applications on noisy quantum computers.
