Researchers have developed a new approach that can precisely count from zero to more than 9,000 individual photons. The advance opens new possibilities for studying quantum light at large scales and making precise optical measurements.
A new setup with eight superconducting sensors can now count more than 9,000 photons per pulse, although it distributes the light only on 1,024 measuring channels. However, a measurement uncertainty of less than one photon reaches the process only up to 276 photons. Paderborn (Germany). For photonics [...] The article Multiplexed detector system counts more than 9,000 photons from light pulses first appeared on scanxx
