摘要:

为了建立量子纠缠信令在自由空间传输时的损伤模型,提出了信令传输损伤度与传输距离的关系,给出了量子信令的中继方案和信令损伤修复策略。仿真结果表明,在收、发两端望远镜的孔径数值、传输因子和载体光子的波长三个参数一定的情况下,传输损伤度与距离、定位损耗密切相关,定位损耗的变化对信令传输损伤度影响很小。因此,影响信令传输损伤度的主要因素是通信距离,量子信令在自由空间的远距离传送需要增加中继器。

Abstract:

To build the transmission damage model of quantum entanglement singling in free space, the relationship between transmission distance and singling damage degree was proposed. A relay scheme of quantum entanglement signaling and its repairing strategy were put forward. The simulation results show that transmission damage degree is closely related to transmission distance and positioning loss under the three conditions of the telescope's aperture of the sending and receiving ends and transmission factor and the carrier photons wavelength are constant. And the positioning loss has a little effect on the transmission damage degree. Therefore, the transmission distance is the main factor of the signaling damage. Quantum signaling long distance transmission in free space has to depend on repeaters.

Key words: quantum optics, singling damage model, quantum entanglement signaling, transmission damage degree, quantum relay
