Experts have integrated thousands of single photon detectors onto a silicon chip, similar to that found in a digital camera.

These photons were then collected with a very simple optical setup, and sent to be detected and analyzed using single photon detectors.

The new system also includes one of the fastest detectors available for single photon counting, a superconducting nanowire single photon detector (SNSPD).

Not exact matches

The detector enables imaging in so - called single photon counting regime allowing acquiring radiographs with theoretically unlimited dynamic range (in practice limited just by the number of detected photons).

For their system, the researchers set a laser next to a highly sensitive photon detector, which can record even a single particle of light.

In previous arrays, the detectors registered only 0.2 percent of the single photons directed at them.

Single - photon detectors are notoriously temperamental: Of 100 deposited on a chip using standard manufacturing techniques, only a handful will generally work.

Secondly, parts of their lab had to be moved to two locations in the city, which as Tittel explains was particularly tricky for the measurement station at City Hall which included state - of - the - art superconducting single - photon detectors developed by the National Institute for Standards and Technology, and NASA's Jet Propulsion Laboratory.

Krivitsky notes that rod - cell efficiency is comparable to the quantum efficiencies of state - of - the - art human - made single - photon detectors such as photomultipliers (40 per cent) and avalanche photodiodes (50 per cent); remarkably, rod cells occupy an area of only 5 by 50 micrometers and contain their own power supply.

Miniature light detectors in frog eyes known as retinal rod cells are directly and unambiguously shown to detect single photons of light — an astounding sensitivity considering that a humble 60 watt light bulb spews out a staggering 1020 photons per second.
