“…Suitable on-chip resistance or inductance was added to weaken the latching effect. [10][11][12] In fact, as long as the positive feedback energy disappears, latching may not happen, The electronics of SNSPD shown in Fig. 1 include a bias circuit and a readout circuit, which are connected to the detector through a bias-tee (bandwidth:…”

Abstract:Latching is a serious issue in superconducting nanowire single-photon detector (SNSPD) technology. By extensively studying the electrical transportation characteristics of SNSPD with different bias schemes, we conclude that latching is a result of the improper bias to SNSPD. With the quasi-constant-voltage bias scheme, the intrinsic nonlatching nature of SNSPD is observed and discussed. The SNSPD working in the nonlatching bias shows a smaller jitter and a higher pulse amplitude than that in the previous anti-latching method. The quantum efficiency of SNSPD with the pulsed photon frequency up to 3 GHz is measured successfully, which further proves the nonlatching operation of SNSPD.

“…As is often the case in applied nanotechnology, devices based on nano-structured elements have to reach micro-meter (SSPD for photon detection applications) or even millimetre A smart solution to overcome this inconvenience is provided by the pure parallel architecture (we call it the Type-0 configuration) as proposed by Ejrnaes et al [42][43] where two or more nano-strips are assembled in parallel. In figure 7 …”

We review progress in the development and applications of superconducting nano-strip particle detectors. Particle detectors based on superconducting nano-strips stem from the parent devices developed for single-photon detection (SSPD) and share with them ultrafast response time (sub-nanosecond) and operation at a relatively high temperature (2 -5 K) with respect to other cryogenic detectors. SSPDs have been used in the detection of electrons, neutral and charged ions, and biological macromolecules. Nevertheless, the development of superconducting nano-strip particle detectors has been mainly driven by the use in time-of-flight mass spectrometers (TOF-MS) where the goal of 100% efficiency at large mass values can be obtained. A special emphasis will be given to this case, reporting the great progress achieved which permits to overcome the limitations of existing mass spectrometers represented by low detection efficiency at large masses and charge/mass ambiguity and could represent a breakthrough in the field. In this review article we will introduce the device concept and detection principle, stressing the peculiarities of the nano-strip particle detector as well as its similarities with the photon detector. The development of the parallel strip configuration is introduced and extensively discussed, since it has contributed to significant progress in TOF-MS applications.

“…To achieve reaso− nable area coverage very long meandered nanowires have been used, but this detector configuration is not well suited to meet demands of higher energy sensitivity or large area coverage because it looses speed, due to the large kinetic inductance L kin . A series connection of blocks made of pa− rallel nanowires can be used to significant increase the area coverage with no loss in key detector characteristics such as efficiency and speed [96]. The parallel SSPDs working principle is based on the cascade switch mechanism [97].…”

The progress in nanofabrication has made possible the realization of optic nanodevices able to handle single photons and to exploit the quantum nature of single-photon states. In particular, quantum cryptography (or more precisely quantum key distribution, QKD) allows unconditionally secure exchange of cryptographic keys by the transmission of optical pulses each containing no more than one photon. Additionally, the coherent control of excitonic and photonic qubits is a major step forward in the field of solid-state cavity quantum electrodynamics, with potential applications in quantum computing. Here, we describe devices for realization of single photon generation and detection based on high resolution technologies and their physical properties. Particular attention will be devoted to the description of single-quantum dot sources based on photonic crystal microcavites optically and electrically driven: the electrically driven devices is an important result towards the realization of single photon source “on demand”. A new class of single photon detectors, based on superconducting nanowires, the superconducting single-photon detectors (SSPDs) are also introduced: the fabrication techniques and the design proposed to obtain large area coverage and photon number-resolving capability are described.
