    "abstract": "We investigate the concentration of multi-party entanglement by focusing on\nsimple family of three-partite pure states, superpositions of\nGreenberger-Horne-Zeilinger states and singlets. Despite the simplicity of the\nstates, we show that they cannot be reversibly concentrated by the standard\nentanglement concentration procedure, to which they seem ideally suited. Our\nresults cast doubt on the idea that for each N there might be a finite set of\nN-party states into which any pure state can be reversibly transformed. We\nfurther relate our results to the concept of locking of entanglement of\nformation.",
