    "abstract": "Parity measurements on qubits can generate the entanglement resource\nnecessary for scalable quantum computation. Here we describe a method for fast\noptical parity measurements on electron spin qubits within coupled quantum\ndots. The measurement scheme, which can be realised with existing technology,\nconsists of the optical excitation of excitonic states followed by monitored\nrelaxation. Conditional on the observation of a photon, the system is projected\ninto the odd/even parity subspaces. Our model incorporates all the primary\nsources of error, including detector inefficiency, effects of spatial\nseparation and non-resonance of the dots, and also unwanted excitations.\nThrough an analytical treatment we establish that the scheme is robust to such\neffects. Two applications are presented: a realisation of a CNOT gate, and a\ntechnique for growing large scale graph states.",
