In this work we investigate the existence of bound states for doubly heavy tetraquark systems Q-Q- 'qq' in a full lattice-QCD computation, where heavy bottom quarks are treated in the framework of non-relativistic QCD. We focus on three systems with quark content b-b-ud, b-b-us and b-c-ud. We show evidence for the existence of b-b-ud and b-b-ud bound states, while no binding appears to be present for b-c-ud. For the bound four-quark states we also discuss the importance of various creation operators and give an estimate of the meson-meson and diquark-antidiquark percentages.
