Optimization of Superconducting Niobium Nitride Thin Films via High-Power Impulse Magnetron Sputtering
Hudson T. Horne, Collin M. Hugo, Brandon C. Reid +1
We report a systematic comparison of niobium nitride thin films deposited on oxidized silicon substrates by reactive DC magnetron sputtering and reactive high-power impulse magnetr…
50 Ohm Transmission Lines with Extreme Wavelength Compression Based on Superconducting Nanowires on High-Permittivity Substrates
Daniel F. Santavicca, Marco Colangelo, Carleigh R. Eagle +2
We demonstrate impedance-matched low-loss transmission lines with a signal wavelength more than 150 times smaller than the free space wavelength using superconducting nanowires on…
A compact and tunable forward coupler based on high-impedance superconducting nanowires
Marco Colangelo, Di Zhu, Daniel F. Santavicca +3
Developing compact, low-dissipation, cryogenic-compatible microwave electronics is essential for scaling up low-temperature quantum computing systems. In this paper, we demonstrate…
Superconducting nanowire single-photon detector with integrated impedance-matching taper
Di Zhu, Marco Colangelo, Boris A. Korzh +11
Conventional readout of a superconducting nanowire single-photon detector (SNSPD) sets an upper bound on the output voltage to be the product of the bias current and the load imped…
Jitter Characterization of a Dual-Readout SNSPD
D. F. Santavicca, B. Noble, C. Kilgore +4
To better understand the origins of the timing resolution, also known as jitter, of superconducting nanowire single-photon detectors (SNSPDs), we have performed timing characteriza…
A distributed electrical model for superconducting nanowire single photon detectors
Qing-Yuan Zhao, Daniel F. Santavicca, Di Zhu +2
To analyze the switching dynamics and output performance of a superconducting nanowire single photon detector (SNSPD), the nanowire is usually modelled as an inductor in series wit…
