We apply the integrability-based Quantum Spectral Curve framework to study the exact quark-antiquark potential in planar N=4 supersymmetric Yang-Mills theory. We focus on the singular limit corresponding to the flat space potential. We present weak coupling results to 7 loops and a numerical solution in a wide range of the coupling. We also show that in a special limit the QSC reduces to a Schrodinger equation resumming ladder diagrams to all perturbative orders.
