Abstract
Section titled āAbstractāHighly entangled graph states of photons have applications in universal\nquantum computing and in quantum communications. In the latter context, they\nhave been proposed as the key ingredient in the establishment of long-distance\nentanglement across quantum repeater networks. Recently, a general\ndeterministic approach to generate repeater graph states from quantum emitters\nwas given. However, a detailed protocol for the generation of such states from\nrealistic systems is still needed in order to guide experiments. Here, we\nprovide such explicit protocols for the generation of repeater graph states\nfrom two types of quantum emitters: NV centers in diamond and self-assembled\nquantum dots. A crucial element of our designs is an efficient controlled-Z\ngate between the emitter and a nuclear spin, used as an ancilla qubit.\nAdditionally, a fast protocol for using pairs of exchange-coupled quantum dots\nto produce repeater graph states is described. Our focus is on near-term\nexperiments feasible with existing experimental capabilities.\n
