Q-FARM presents "Scaling-up single-photon quantum hardware towards quantum-information processing with a quantum advantage"
Semiconductor quantum dots embedded in photonic nanostructures offer a highly efficient and coherent deterministic photon-emitter interface . It constitutes an on-demand single-photon source for quantum-information applications, enables single-photon nonlinear, optics and the constructing of deterministic quantum gates for photons . We review recent experimental progress, and demonstrate that the current technology can be scaled up to reach quantum advantage  with the demonstration of near-transform-limited emitters in high-cooperativity planar nanophotonic waveguides . The coherent control of a single spin in the quantum dot [5, 6] offers additional opportunities of generating advanced multi-photon entangled states . We finally discuss how this emergent hardware may be applied in a resource-efficient manner, e.g., for constructing a one-way quantum repeater .
