Recent work using a large-charge expansion for the $O(N)$ Wilson-Fisherconformal field theory has shown that the anomalous dimensions of large-chargeoperators can be expressed in terms of a few low-energy constants (LECs) of alarge-charge effective field theory (EFT). By performing lattice Monte Carlocomputations at the $O(N)$ Wilson-Fisher fixed point, we compute the anomalousdimensions of large-charge operators up to $N=8$ and charge $Q=10$, and extractthe leading and subleading LECs of the $O(N)$ large-charge EFT. To alleviatethe signal-to-noise ratio problem present in the large-charge sector ofconventional lattice formulations of the $O(N)$ theory, we employ a recentlydeveloped qubit formulation of the $O(N)$ nonlinear sigma models with a wormalgorithm. This enables us to test the validity of the large-charge expansionand the recent large-$N$ predictions for the coefficients of the large-chargeEFT.
