We study superflow decay via quantum phase slips in trapped one-dimensional(1D) quantum gases through dipole oscillations induced by sudden displacementof the trapping potential. We find the relation between the damping rate of thedipole oscillation $G$ and the phase-slip nucleation rate $\Gamma$ as $G\propto\Gamma/v$, where $v$ is the flow velocity. This relation allows us to show thatdamping of 1D Bose gases in optical lattices, which has been extensivelystudied in experiment, is due to quantum phase slips. It is also found that thedamping rate versus the flow velocity obeys the scaling formula for an impuritypotential even in the absence of an explicit impurity. We suggest that thedamping rate at a finite temperature exhibits a universal crossover behaviorupon changing the flow velocity.
