TL;DR: The SFQ interface circuit simplifies the SNSPD readout and enables large numbers of detectors for future compact multi-pixel systems with single photon counting resolution, thus enabling count-rates of several gigahertz.

TL;DR: An efficient multiplexing technique for superconducting nanowire single-photon detectors based on an orthogonal detector bias switching method enabling the extraction of the average count rate of a set of detectors by one readout line is proposed.

TL;DR: In this article, the authors present an assessment of different approaches for reducing the static power consumption by investigating the potential of inductive bias distribution networks as well as reduced critical currents and inductive biasing.

TL;DR: In this paper, the gray zone dependency on the clock frequency of a Josephson comparator is investigated by simulations concerning the influence of thermal noise, which is performed for a series of operating points defined by the bias current and different noise levels defined by operating temperature.

TL;DR: This work analyzes the influence of the bias current on the gray zone of a Josephson comparator and derives a derived normalized dependency that enables the design to certain applications to realize the best trade-off between clock frequency and grey zone.
