Single photon detectors

Single photon detectors are highly sensitive devices designed to identify individual particles of light, called photons. They can detect even the faintest light signals, which is essential in fields like quantum communication and advanced imaging. When a photon hits the detector, it triggers a measurable response, confirming its arrival. These detectors often use materials or technologies that convert the photon’s energy into an electrical signal, allowing precise timing and measurement. Their ability to detect single photons enables cutting-edge research and applications where controlling and understanding light at its most fundamental level is crucial.
