摘要: We report the first experimental demonstration of a quantum controlled-NOT gate for different photons, which is classically feed forwardable. In experiment, we achieved this goal with only use linear optics, an entangled ancillary pair and postselection. The techniques developed in our experiment are significant importance information processing optics.
