Impedance-matched differential superconducting nanowire detectors
Marco Colangelo, Boris Korzh, Jason P. Allmaras +24
Superconducting nanowire single-photon detectors (SNSPDs) are the highest performing photon-counting technology in the near-infrared (NIR). Due to delay-line effects, large area SN…
Electrical Control of Surface Acoustic Waves
Linbo Shao, Di Zhu, Marco Colangelo +7
Acoustic waves at microwave frequencies have been widely used in wireless communication and recently emerged as versatile information carriers in quantum applications. However, mos…
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…
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…
