Abstract
(EN)
A device that is a combination of a superconducting nanowire single-photon detector and a superconducting multi-level memory. These devices can be used to count a number of photons impinging on the device through single-photon to single-flux conversion. Electrical characterization of the device demonstrates single-flux quantum (SFQ) separated states. Optical measurements using attenuated laser pulses with different mean photon number, pulse energies and repetition rates are shown to differentiate single-photon detection from other possible phenomena, such as multiphoton detection and thermal activation. Array devices and methods are also discussed.

L'invention concerne un dispositif qui est une combinaison d'un détecteur de photon unique à nanofil supraconducteur et d'une mémoire à niveaux multiples supraconductrice. Ces dispositifs peuvent être utilisés pour compter un nombre de photons frappant le dispositif par le biais d'une conversion de photon unique en flux unique. La caractérisation électrique du dispositif démontre des états séparés de quantum à flux unique (SFQ). Des mesures optiques utilisant des impulsions laser atténuées avec un nombre de photons moyen différent, des énergies d'impulsion et des vitesses de répétition ont démontré différencier une détection de photon unique d'autres phénomènes possibles, tels qu'une détection de photons multiples et une activation thermique. L'invention concerne également des dispositifs matriciels et des procédés.
