We report an experimental demonstration of a bit-flip error-rejection protocol for error-reduced 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 parity measurement, successfully rejecting the erroneous transmission over the noisy quantum channel.
我们报告了一种用于通过有噪声量子信道进行量子信息误差降低传输的比特翻转错误拒绝协议的实验演示。在实验中，待传输的未知状态被编码为双光子纠缠态，然后通过一个经过设计的有噪声量子信道发送。在最后阶段，通过奇偶性测量对未知状态进行解码，成功拒绝了有噪声量子信道上的错误传输。
