A new photon detector called PEACOQ can register the arrival times of individual photons with the best timing resolution to date. Developed by Matthew Shaw and colleagues at NASA’s Jet Propulsion ...

The detector operates on the principle of two-photon absorption (TPA) such that, ideally, it will only register a detection event when it absorbs two incoming photons within a time interval less ...

Scientists have developed the world's most efficient single photon detector, which is able to count individual particles of light traveling through fiber optic cables with roughly 99 percent ...

NIST scientists have developed the world's most efficient single photon detector, which is able to count individual particles of light traveling through fiber optic cables with roughly 99 percent ...

The single photon detector being developed leverages the Quanta Image Sensor (QIS) semiconductor chip shown above. NASA announced it is awarding a team of researchers from Rochester Institute of ...

A single-photon detector that could boost the performance of some quantum key distribution (QKD) cryptography systems has been unveiled by Hugo Zbinden and colleagues at the University of Geneva and ...

High-energy photon detectors (from deep ultraviolet (DUV) to X-rays) are crucial for various fields, including national security, medicine, industrial science and so on.

NIST researchers have unveiled a new kind of single-photon detector array that can identify individual particles of light (photons). It's useful for spectroscopy, where scientists observe how ...

Measurements are funny things sometimes. It is, on the whole, pretty easy to detect light. It is even pretty easy to detect single photons. But a single photon has very little energy in it, so a ...
