论文摘要
基于空间的量子技术是全球量子网络的重要组成部分。但是,所使用的光电组件可能易受辐射损伤。在辐射存在下预测长期仪器性能仍然是太空任务的挑战。我们提出了一个模型,该模型可以解释辐射屏蔽的差异,并可以预测空间基硅Geiger模式雪崩光电二极管(GM-APD)的暗计数的趋势。我们发现,预测的趋势与GM-APD在Spooqy-1 Cubesat Mission上的原位观察结果相关。
Space-based quantum technologies are essential building blocks for global quantum networks. However, the optoelectronic components used can be susceptible to radiation damage. Predicting long-term instrument performance in the presence of radiation remains a challenging part of space missions. We present a model that accounts for differences in radiation shielding and can predict the trends for dark count rates of space-based silicon Geiger-mode avalanche photodiodes (GM-APD). We find that the predicted trends are correlated with in-situ observations from GM-APDs on-board the SpooQy-1 CubeSat mission.
