Whereas Berry curvature\u2013mediated transport effects have been identified in several magnetic and nonmagnetic systems, quantum metric\u2013induced transport phenomena remain limited to topological antiferromagnets. Here, we show that spin-momentum locking, a general characteristic of the electronic states at surfaces and interfaces of spin-orbit\u2013coupled materials, leads to a finite quantum metric. This metric activates a nonlinear in-plane magnetoresistance that we measured and electrically controlled in 111-oriented LaAlO\n                    <jats:sub>3<\/jats:sub>\n                    \/SrTiO\n                    <jats:sub>3<\/jats:sub>\n                    interfaces.
