# The Zero-Error Entanglement Cost is Highly Non-Additive

Qiuling and I have recently posted a paper on the arXiv that studies the zero-error entanglement cost its regularized version for maximally correlated bipartite states. Using techniques from the resource theory of coherence, we show that it is possible to generate $$n$$ copies of certain entangled states using the same amount of entanglement needed to generated just a single copy.
