    "abstract": "We describe a laboratory demonstration of a quantum error correction\nprocedure that can correct intrinsic measurement errors in linear-optics\nquantum gates. The procedure involves a two-qubit encoding and fast\nfeed-forward-controlled single-qubit operations. In our demonstration the\nqubits were represented by the polarization states of two single-photons from a\nparametric down-conversion source, and the real-time feed-forward control was\nimplemented using an electro-optic device triggered by the output of\nsingle-photon detectors.",
