提出了两个抗联合噪声的确定的安全量子通信方案.一个用于在联合转动噪声下进行安全的量子通信,另一个用于在联合退相位噪声下进行安全的量子通信.量子通信的双方利用他们的子系统之间的量子关联有效地完成窃听检测.为了在联合噪声下进行安全的量子通信,发送方需要制备一串三光子纠缠态,但通信双方仅需要采用单光子测量获得信息,而不是Bell态测量.这一特点使得我们的方案在实际应用中更方便.
Two secure quantum communication schemes against combined noise are proposed, one for secure quantum communication with joint rotation noise and the other for secure quantum communication with joint decoherence noise. Both quantum communication are exploited The quantum correlation between their subsystems effectively completes the eavesdropping detection.In order to make secure quantum communication under joint noises, the sender needs to prepare a string of three-photon entangled states, but the communicating parties only need to obtain the information by single-photon measurements, Not Bell state measurement.This feature makes our program more convenient in practical application.
