SOURCE REVIEW

Single-photon detectors and cryogenic components

What this establishes—and its limits

The configurable channel count is a product configuration, not a detector-efficiency result. The catalog does not establish identical performance across every chip, wavelength and cryostat.

Evidence to look for next

Compare detection efficiency, timing jitter, dark counts, recovery time and cooling requirements together.
