Single-photon detectors based on superconducting nanowires (SSPDs or SNSPDs) have
rapidly emerged as a highly promising photon-counting technology for infrared wavelengths …

We have fabricated and tested superconducting single-photon detectors and demonstrated
detection efficiencies of 57% at 1550-nm wavelength and 67% at 1064 nm. In addition to the …

We report the development of a photon-number-resolving detector based on a fiber-optical
setup and a pair of standard avalanche photodiodes. The detector is capable of resolving …

For photon-counting applications at ultraviolet wavelengths, there are currently no detectors
that combine high efficiency (> 50%), sub-nanosecond timing resolution, and sub-Hz dark …

We report our studies on spectral sensitivity of meander-type, superconducting NbN thin-film
single-photon detectors SPDs, characterized by GHz counting rates of visible and near …

Detectors that can resolve photon number are needed in many quantum information
technologies. In order to be useful in quantum information processing, such detectors should …

Modeling of superconducting nanowire single-photon detectors typically requires custom
simulations or finite-element analysis in one or two dimensions. Here, we demonstrate two …

Fabrication of NbN superconducting single-photon detectors, based on the hotspot effect is
presented. The hotspot formation arises in an ultrathin and submicrometer-width …

Nanoelectronics is changing the way the world communicates, and is transforming our daily
lives. Continuing Moore's law and miniaturization of low-power semiconductor chips with …

We present a new class of ultrafast single-photon detectors for counting both visible and
infrared photons. The detection mechanism is based on photon-induced hotspot formation …
