IdealPhotonics' single-photon detection technology utilizes ultra-sensitive sensors (such as avalanche photodiodes/superconducting nanowires) to detect and count individual photon events, enabling quantitative measurement of extremely weak light signals. Key performance indicators include detection efficiency, dark count rate, and time jitter.Single-photon-level sensitivity and picosecond-level time resolution, achieved through noise suppression and precise time-domain labeling, break through the limits of classical detection, supporting quantum technology and weak light analysis.
