Realization of a photonic CNOT gate sufficient for quantum computation
arXiv:quant-ph/0404107 · doi:10.1103/PhysRevLett.93.020504
Abstract
We report the first experimental demonstration of a quantum controlled-NOT gate for different photons, which is classically feed-forwardable. In the experiment, we achieved this goal with the use only of linear optics, an entangled ancillary pair of photons and post-selection. The techniques developed in our experiment will be of significant importance for quantum information processing with linear optics.
