In particular, Parton distribution functions (PDFs), which capture the longitudinal momentum structure of fast-moving nucleons, are defined on the light cone and are not directly accessible in Euclidean lattice QCD. I will draw together two relatively new ideas, quasi distributions and the gradient flow, to demonstrate how these ideas can help circumvent some of the issues facing ab initio calculations of PDFs.</span></span></tt><tt
