论文摘要
我们采用人工$λ$ -Type三级系统,带有超导设备用于微波信号检测,在该设备中,信号强度达到离散光子的水平而不是连续波形。基于三级系统的状态过渡原理,我们提出了一个微波信号检测的统计模型。此外,我们根据统计模型研究了可实现的传输速率和信号检测。可以预测,与当前部署的4G/5G通信系统相比,提出的检测可以实现明显更高的灵敏度。我们进一步表征了饱和度征的接收信号,该信号揭示了由于弱接收的功率状态下饱和度引起的可忽略不计的性能降解。
We adopt artificial $Λ$-type three-level system with superconducting devices for microwave signal detection, where the signal intensity reaches the level of discrete photons instead of continuous waveform. Based on the state transition principles of the three-level system, we propose a statistical model for microwave signal detection. Moreover, we investigate the achievable transmission rate and signal detection based on the statistical model. It is predicted that the proposed detection can achieve significantly higher sensitivity compared with the currently deployed 4G/5G communication system. We further characterize the received signal considering the saturation phonomenon, which reveals negligible performance degradation caused by saturation under weak received power regime.
