The thermally-coupled imager: A scalable readout architecture for superconducting nanowire single photon detectors
Adam N. McCaughan, Yao Zhai, Boris Korzh +4
Although superconducting nanowire single-photon detectors (SNSPDs) are a promising technology for quantum optics, metrology, and astronomy, they currently lack a readout architectu…
PHIDL: Python CAD layout and geometry creation for nanolithography
A. N. McCaughan, A. M. Tait, S. M. Buckley +4
Computer-aided design (CAD) has become a critical element in the creation of nanopatterned structures and devices. In particular, with the increased adoption of easy-to-learn progr…
Frequency pulling and mixing of relaxation oscillations in superconducting nanowires
Emily Toomey, Qing-Yuan Zhao, Adam N. McCaughan +1
Many superconducting technologies such as rapid single flux quantum computing (RSFQ) and superconducting quantum interference devices (SQUIDs) rely on the modulation of nonlinear d…
Sensing supercurrents using geometric effects
Adam N. McCaughan, Nathnael Abebe, Qing-Yuan Zhao +1
We describe a superconducting three-terminal device that uses a simple geometric effect known as current crowding to sense the flow of current and actuate a readout signal. The dev…
Microwave dynamics of high aspect ratio superconducting nanowires studied using self-resonance
Daniel F. Santavicca, Jesse K. Adams, Lierd E. Grant +2
We study the microwave impedance of extremely high aspect ratio (length/width ~ 5,000) superconducting niobium nitride nanowires. The nanowires are fabricated in a compact meander…
Universal scaling of the critical temperature for thin films near the superconducting-to-insulating transition
Yachin Ivry, Chung-Soo Kim, Andrew E. Dane +5
Thin superconducting films form a unique platform for geometrically-confined, strongly-interacting electrons. They allow an inherent competition between disorder and superconductiv…
A superconducting-nanowire 3-terminal electronic device
Adam N. McCaughan, Karl K. Berggren
In existing superconducting electronic systems, Josephson junctions play a central role in processing and transmitting small-amplitude electrical signals. However, Josephson-juncti…
