    "abstract": "We describe an experimentally straightforward method for preparing an\nentangled W state of up to 100 qubits. Our repeat-until-success protocol relies\non detection of single photons from collective spontaneous emission in free\nspace. Our method allows entanglement preparation in a wide range of qubit\nimplementations that lack entangling qubit-qubit interactions. We give detailed\nnumerical examples for entanglement of neutral atoms in optical lattices and of\nnitrogen-vacancy centres in diamond. The simplicity of our method should enable\npreparation of mesoscopic entangled states in a number of physical systems in\nthe near future.",
