Any deterministic bipartite entanglement transformation involving finite copies of pure states and carried out using local operations and classical communication (LOCC) results in a net loss of entanglement. We show that for almost all such transformations, partial recovery of lost entanglement is achievable by using 2× 2 auxiliary entangled states, no matter how large the dimensions of the par...

We show that partial recovery of entanglement in an entanglement transformation is almost always possible irrespective of dimensions. Let |ψ〉 and |φ〉 be n × n states and |ψ〉 −→ |φ〉 under local operations. We ask whether there exists k × k states, |χ〉 and |ω〉, k < n where E (|ω〉) > E (|χ〉), E being the entropy of entanglement such that |ψ〉⊗|χ〉 −→ |φ〉⊗|ω〉 under LOCC. We show that for almost all p...
