  Title Counting photons using a nanonetwork of superconducting wires Type Conference Article
  Year 2009 Publication Nano-Net Abbreviated Journal  
  Volume Issue Pages 120-122  
  Keywords (down) SSPD, SNSPD  
  Abstract We show how the parallel connection of photo-sensitive superconducting nanowires can be used to count the number of photons in an optical pulse, down to the single-photon level. Using this principle we demonstrate photon-number resolving detectors with unprecedented sensitivity and speed at telecommunication wavelengths.

  Title High speed infrared photon counting with photon number resolving superconducting single-photon detectors (SSPDs) Type Conference Article
  Year 2009 Publication CLEO/Europe – EQEC Abbreviated Journal CLEO/Europe – EQEC  
  Volume Issue Pages  
  Keywords (down) SSPD, SNSPD  
  Abstract A review of development and characterization of the nanostructures consisting of several meander sections, all connected in parallel was presented. Such geometry leads to a significant decrease of the kinetic inductance, without a decrease of the SSPD active area. A new type of SSPDs possess the QE of large-active- area devices, but, simultaneously, allows achieving short response times and the GHz-counting rate. This new generation of superconducting detectors has another significant advantage for quantum key distribution, they have a photon number resolving capability and can distinguish more photons.

  Title Superconducting nanowire single-photon detectors for quantum information and communications Type Journal Article
  Year 2009 Publication IEEE J. Sel. Topics Quantum Electron. Abbreviated Journal  
  Volume 15 Issue 6 Pages 1741-1747  
  Keywords (down) SSPD  
  Abstract Superconducting nanowire single-photon detectors (SNSPDs or SSPD) are highly promising devices in the growing field of quantum information and communications technology. We have developed a practical SSPD system with our superconducting thin films and devices fabrication, optical coupling packaging, and cryogenic technology. The SSPD system consists of six-channel SSPD devices and a compact Gifford-McMahon (GM) cryocooler, and can operate continuously on 100 V ac power without the need for any cryogens. The SSPD devices were fabricated from high-quality niobium nitride (NbN) ultrathin films that were epitaxially grown on single-crystal MgO substrates. The packaged SSPD devices were temperature stabilized to 2.96 K ± 10 mK. The system detection efficiency for an SSPD device with an area of 20 × 20 ¿m2 was found to be 2.6% and 4.5% at wavelengths of 1550 and 1310 nm, respectively, at a dark count rate of 100 Hz, and a jitter of 100 ps full-width at half maximum. We also performed ultrafast BB84 quantum key distribution (QKD) field testing and entanglement-based QKD experiments using these SSPD devices.

  Title Ультрабыстрый однофотонный детектор для оптических применений Type Conference Article

  Volume Issue Pages 45-46  
  Keywords (down) SSPD  
  Abstract Представлен сверхпроводниковый однофотонный детектор (SSPD) на основе ультратонкой пленки NbN, обладающий рекордным быстродействием. Активный элемент выполнен в виде N сверхпроводящих полосок соединенных параллельно, покрывающих площадку размером 10 мкм х 10 мкм. Для SSPD с N=12 длительность импульса напряжения составляет 200 пс. Полученные результаты открывают путь к детекторам обладающими скоростью счета свыше 1 ГГц, что делает SSPDs весьма привлекательными во многих применениях, в частности для квантовой криптографии. SSPD хорошо согласуется с оптоволокном и легко может быть интегрирован в полностью готовую для работы приемную систему.

  Title Single-photon detectors for optical quantum information applications Type Journal Article
  Year 2009 Publication Nature Photonics Abbreviated Journal Nature Photonics  
  Volume 3 Issue Pages 696-705  
  Keywords (down) SPD  
  Abstract The past decade has seen a dramatic increase in interest in new single-photon detector technologies. A major cause of this trend has undoubtedly been the push towards optical quantum information applications such as quantum key distribution. These new applications place extreme demands on detector performance that go beyond the capabilities of established single-photon detectors. There has been considerable effort to improve conventional photon-counting detectors and to transform new device concepts into workable technologies for optical quantum information applications. This Review aims to highlight the significant recent progress made in improving single-photon detector technologies, and the impact that these developments will have on quantum optics and quantum information science.

  Title Suppressed critical current in superconducting nanowire single-photon detectors with high fill-factors Type Journal Article
  Year 2009 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal  
  Volume 19 Issue 3 Pages 318-322  
  Keywords (down) SNSPD  
  Abstract In this work we present a new fabrication process that enabled the fabrication of superconducting nanowire single photon detectors SNSPD with fill-factors as high as 88% with gaps between nanowires as small as 12 nm. This fabrication process combined high-resolution electron-beam lithography with photolithography. Although this work was motivated by the potential of increased detection efficiency with higher fill-factor devices, test results showed an unexpected systematic suppression in device critical currents with increasing fill-factor.
