We review the current status of single-photon-source and single-photon-detector
technologies operating at wavelengths from the ultraviolet to the infrared. We discuss …

Over the past several decades, quantum information science has emerged to seek answers
to the question: can we gain some advantage by storing, transmitting and processing …

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 …

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

Ultrafast, high-efficiency single-photon detectors are among the most sought-after elements
in modern quantum optics and quantum communication. However, imperfect modal …

The use of nanowires and nanowire structures as photodetectors is an emerging research
topic. Despite the large amount of reports on nanowire photoresponse that appeared in the …

The detection and generation of single photons has seen an upsurge in interest in recent
years as new scientific fields of research, for example quantum information processing, have …

We have measured the magnetotransport properties and Hall effect of a series of epitaxial
NbN films grown on (100) oriented single crystalline MgO substrate under different …

We investigate the role of electrothermal feedback in the operation of superconducting
nanowire single-photon detectors (SNSPDs). It is found that the desired mode of operation …

We report the evolution of the magnetic penetration depth (λ) and superconducting energy
gap (Δ) in epitaxial NbN films with thickness (d) varying between 51–3 nm. With decrease in …
