    "abstract": "We describe a novel protocol for a quantum repeater which enables long\ndistance quantum communication through realistic, lossy photonic channels.\nContrary to previous proposals, our protocol incorporates active purification\nof arbitrary errors at each step of the protocol using only two qubits at each\nrepeater station. Because of these minimal physical requirements, the present\nprotocol can be realized in simple physical systems such as solid-state single\nphoton emitters. As an example, we show how nitrogen vacancy color centers in\ndiamond can be used to implement the protocol, using the nuclear and electronic\nspin to form the two qubits.",
