“…We should note that high‐ T c superconductors, such as the cuprates, have not been successfully implemented as SNSPDs, perhaps the high energy gap is too large to allow single‐photon detection. Yet, nanowires made of high‐ T c superconductors have already been implemented as sensitive photon detectors (not single photons) . Recently, by looking at the dark counts of YBCO nanowires, Ejrnaes et al .…”

Single-photon detectors and nanoscale superconducting devices are two major candidates for realizing quantum technologies. Superconducting-nanowire single-photon detectors (SNSPDs) comprise these two solid-state and optic aspects enabling high-rate (1.3 Gb s −1 ) quantum key distribution over long distances (>400 km), long-range quantum communication (>1200 km), as well as space communication (239 000 miles). The attractiveness of SNSPDs stems from competitive performance in the four single-photon relevant characteristics at wavelengths ranges from UV to the mid-IR: high detection efficiency, low false-signal rate, low uncertainty in photon time arrival, and fast reset time. However, to date, these characteristics cannot be optimized simultaneously. In this review, the mechanisms that govern these four characteristics are presented, and it is demonstrated how they are affected by material properties and device design as well as by the operating conditions, allowing aware optimization of SNSPDs. Based on the evolution in the existing literature and state of the art, it is proposed how to choose or design the material and device for optimizing SNSPD performance, while possible future opportunities in the SNSPD technology are also highlighted.

“…The current-voltage characteristic of the nanobridges presents a sharp voltage switch, of the order of a few millivolts, from the superconducting state to the resistive state, that we interpret in terms of hot spot formation [22]. This feature, not found in state-of-the-art YBCO nanobridges [23,24], is due to the different thermal conductivity between the two cuprate families and the different thermal boundary resistance between the films and the substrate, making the electron-doped compounds extremely attractive materials to engineer nanowire-based single photon detectors.…”

“…They demonstrated the effect of bolometric and photoabsorption‐induced transitions using subgap and over‐the‐gap THz radiation. Using pulsed laser deposition technique, Arpaia et al deposited a series of 50 nm thick YBCO layers. Nanostripes of YBCO on LAO substrates with widths varying in the range of 90–500 nm and lengths increasing up to 10 µm proportionally to the width were realized (Figure B,C).…”

Since the discovery of superconductivity at temperatures above the technologically promising liquid nitrogen temperatures, applications based on superconductors have expanded and are being put to commercial use. However, superconductivity at higher temperatures typically occurs in complex materials requiring stringent material and environmental constraints. Such restraints make the realization and integration of these materials with normal materials a nontrivial aspect. In this progress report, unique features of these superconductors in terms of their synthesis, physical properties determining interface electrical transport, and their applications are discussed. A detailed progress report on these applications with remarks on efforts taken to integrate these devices with traditional platforms and semiconducting materials is provided.
