    "abstract": "We report the first experimental demonstration of a quantum controlled-NOT\ngate for different photons, which is classically feed-forwardable. In the\nexperiment, we achieved this goal with the use only of linear optics, an\nentangled ancillary pair of photons and post-selection. The techniques\ndeveloped in our experiment will be of significant importance for quantum\ninformation processing with linear optics.",
