  The (non-)local content in the sense of Elitzur, Popescu, and Rohrlich (EPR2)
[Phys. Lett. A 162, 25 (1992)] is a natural measure for the (non-)locality of
quantum states. Its computation is in general difficult, even in low
dimensions, and is one of the few open questions about pure two-qubit states.
We present a complete solution to this long-lasting problem.
