Constructs a family of embezzling states with Schmidt coefficients ~1/√j (normalization ~log n) that let two separated parties convert a product target into an entangled target by local unitaries with fidelity at least 1 − (log m)/log n, so achieving error ε requires n ~ (1/ε)×(target size) (polynomial blowup). Multiparty embezzlement exists but costs doubly exponential resources. Tools: explicit Schmidt permutations, correlated‑sampling robustness, and uses in quantum games and the quantum reverse Shannon theorem; the schemes work only approximately and require large dimensions.
