In this study, we study static and spherically-symmetric wormhole configurations within the recently proposed class of extended symmetric teleparallel gravities characterised by the functional form f(Q,T)=αQ+βT+γT2, where Q is the non-metricity scalar, T is the trace of the energy-momentum tensor, and (α,β,γ) are constant coupling parameters. By varying the action with respect to the metric, we derive the modified field equations and cast them in an effective Einstein-like form containing additional geometric contributions that depend on Q and T. We conclude that the f(Q,T)=αQ+βT+γT2 framework offers a viable arena for constructing physically realistic wormholes without invoking severe energy condition violations, opening new pathways for connecting modified gravity phenomenology with astrophysical signatures of non-trivial spacetime topologies.
