Strong suppression of the resistivity near the transition to superconductivity in narrow micro-bridges in external magnetic fields
Xiaofu Zhang, Adriana E. Lita, Konstantin Smirnov +5
We have investigated a series of superconducting bridges based on homogeneous amorphous WSi and MoSi films, with bridge widths w ranging from 2 um to 1000 um and film thicknesses d…
A single photon detection system for visible and infrared spectrum range
Alexander Divochiy, Marta Misiaszek, Yury Vakhtomin +4
We demonstrate niobium nitride based superconducting single-photon detectors sensitive in the spectral range 452 nm - 2300 nm. The system performance was tested in a real-life expe…
Superconducting single-photon detectors with saturated dependence of quantum efficiency vs. bias current
Konstantin Smirnov, Alexander Divochiy, Yury Vakhtomin +4
It was investigated the possibility of creating NbN superconducting single-photon detectors with saturated dependence of quantum efficiency versus normalized bias current. It was s…
Single photonics at telecom wavelengths using nanowire superconducting detectors
C. Zinoni, B. Alloing, L. H. Li +7
Single photonic applications - such as quantum key distribution - rely on the transmission of single photons, and require the ultimate sensitivity that an optical detector can achi…
