Experimental Quantum Error Rejection for Quantum Communication
  We report an experimental realization of bit-flip error rejection for error-free transfer of quantum information through a noisy quantum channel. In the experiment, an unknown state to be transmitted is encoded into a two-photon entangled state, which is then sent through an engineered noisy quantum channel. At the final stage, the unknown state is decoded by a quantum parity measurement, successfully rejecting the erroneous transmission over the noisy quantum channel.
