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

Buy one, get $$n-1$$ free! 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 […]
