WebEvery photon does count, not only in research but also, increasingly, in business. Single-photon detection is at the heart of quantum communications, which offers absolute protection against eavesdropping. The technology is moving out of test beds and is being employed in some important settings. For example, quantum equipment from Geneva … WebIf you need to count photons or to precisely tag photons arrival times, we are the people you are looking for. ...

WebThe quantum efficiency states that for every photon coming in there’s a probability of X % that the photon will generate an electron that is measured by the detector. If a detector has a quantum efficiency of 60%, and 100 photons are impinging on its surface then the detector will count on average 60 electrons. The remaining 40 are lost. WebThe term Single-Photon Avalanche Diode (SPAD) defines a class of photodetectors able to detect low intensity signals (down to the single photon) and to signal the time of the photon arrival with high temporal … chingons
