    "abstract": "Entanglement in the ground state of a many-body quantum system may arise when\nthe local terms in the system Hamiltonian fail to commute with the interaction\nterms in the Hamiltonian. We quantify this phenomenon, demonstrating an analogy\nbetween ground-state entanglement and the phenomenon of frustration in spin\nsystems. In particular, we prove that the amount of ground-state entanglement\nis bounded above by a measure of the extent to which interactions frustrate the\nlocal terms in the Hamiltonian. As a corollary, we show that the amount of\nground-state entanglement is bounded above by a ratio between parameters\ncharacterizing the strength of interactions in the system, and the local energy\nscale. Finally, we prove a qualitatively similar result for other energy\neigenstates of the system.",
