“…They have been applied in several fields including spectroscopy of ultrafast quantum phenomena, 4 optical communications, 5 quantum cryptography, 6 and fast digital circuit testing. 7 On the other hand, a wide potential for superconducting nanoscale detectors used as advanced bolometers is also expected in several astrophysical space applications, where bolometers are promising candidates to meet future needs of cooled telescopes. The interest lies in the negligible Johnson noise they show with a noise equivalent power ͑NEP͒ as low as 10 −18 W / ͱ Hz.…”

We propose a mesoscopic kinetic-inductance radiation detector based on a long superconductor-normal metal-superconductor Josephson junction. The operation of this proximity Josephson sensor relies on large kinetic inductance variations under irradiation due to the exponential temperature dependence of the critical current. Coupled with a dc superconducting quantum interference device readout, the PJS is able to provide a signal to noise (S/N) ratio up to similar to 10(3) in the terahertz regime if operated as calorimeter, while electrical noise equivalent power as low as similar to 7x10(-20) W/root Hz at 200 mK can be achieved in the bolometer operation. The high performance together with the ease of fabrication make this structure attractive as an ultrasensitive cryogenic detector of terahertz electromagnetic radiation.

“…The combination of the high quantum efficiency and high operation rate, small jitter and extremely low spontaneous dark count rate allows carrying out such refine measurements as registration of the optical impulses with picosecond resolution which generates during MOSFET switches. This method is already used for the manufacturing quality control and circuit design testing during microcircuit and microprocessors engineering [13,14].…”

Single-photon detectors (SPDs) are the foundation of all quantum communications (QC) protocols. Among different classes of SPDs currently studied, NbN superconducting SPDs (SSPDs) are established as the best devices for ultrafast counting of single photons in the infrared (IR) wavelength range. The SSPDs are nanostructured, 100 µ m 2 in total area, superconducting meanders, patterned by electron lithography in ultra-thin NbN films. Their operation has been explained within a phenomenological hot-electron photoresponse model. We present the design and performance of a novel, two-channel SPD receiver, based on two fiber-coupled NbN SSPDs. The receivers have been developed for fiber-based QC systems, operational at 1.3 µ m and 1.55 µ m telecommunication wavelengths. They operate in the temperature range from 4.2 K to 2 K, in which the NbN SSPDs exhibit their best performance. The receiver unit has been designed as a cryostat insert, placed inside a standard liquid-helium storage dewar. The input of the receiver consists of a pair of single-mode optical fibers, equipped with the standard FC connectors and kept at room temperature. Coupling between the SSPD and the fiber is achieved using a specially designed, precise micromechanical holder that places the fiber directly on top of the SSPD nanostructure. Our receivers achieve the quantum efficiency of up to 7% for near-IR photons, with the coupling efficiency of about 30%. The response time was measured to be <1.5 ns and it was limited by our read-out electronics. The jitter of fiber-coupled SSPDs is <35 ps and their dark-count rate is below 1s -1 . The presented performance parameters show that our single-photon receivers are fully applicable for quantumcorrelation-type QC systems, including practical quantum cryptography.

“…Such coatings can be widely used for fabrication of Josephson's large integrated circuits [10][11][12][13], bolometers [10]- [15] and superconducting onephoton detectors [1,4,[14][15][16][17][18][19][20][21][22][23][24]. Low thermal stability and oxidation resistance are among the main disadvantages of such coatings.…”

Phase transformations of Al doped NbN nanocomposite coatings are studied in detail focusing on their microstructural evolution and phase composition. Several techniques such as XRD, SEM, HR-TEM, Nanoindentation and molecular dynamics simulation are employed in order to understand the phase evolution of the Nb-Al-N system. The nanocomposite structures were formed in the coatings, the roughness of the coatings decreased with increasing the Al concentration due to decreasing grain size. First-principles investigation of Nb-Al-N solid solutions was carried out to interpret film properties. It was found, that for small Al fractions, the solid solutions will form in agreement with our experimental results. The spinodal decomposition of Nb-Al-N solid solutions is supposed to be responsible for the formation of the nanocomosite structure observed in the deposited Nb-Al-N films.
