    "abstract": "We introduce the distribution of a secret multipartite entangled state in a\nreal-world scenario as a quantum primitive. We show that in the presence of\nnoisy quantum channels (and noisy control operations) any state chosen from the\nset of two-colorable graph states (CSS codewords) can be created with high\nfidelity while it remains unknown to all parties. This is accomplished by\neither blind multipartite entanglement purification, which we introduce in this\npaper, or by multipartite entanglement purification of enlarged states, which\noffers advantages over an alternative scheme based on standard channel\npurification and teleportation. The parties are thus provided with a secret\nresource of their choice for distributed secure applications.",
