Single-photon detection technology has important significance for quantum key distribution and even quantum information technology. It introduces the channel capacity as a yardstick to evaluate the performance of the single-photon avalanche photodiodes (SPADs). Studies show that with respect to various factors such as the device structure, operating voltage, and multiplication regions materials, the introduction of the channel capacity allows performance of SPADs to be theoretically optimize.
