Two-copy distillability of one-copy-undistillable negative-partial-transpose states in every dimension

Whether negative-partial-transpose (NPT) states that are undistillable from one copy become distillable from finitely many copies remains a basic open problem in entanglement theory. We study the canonical two-parameter family of DiVincenzo \textit{et al.}, introduced as a symmetry-reduced testbed for this question. We...
