Enhanced Superconducting Transition Temperature in Electroplated Rhenium
David P. Pappas, Donald E. David, Russell E. Lake +13
We show that electroplated Re films in multilayers with noble metals such as Cu, Au, and Pd have an enhanced superconducting critical temperature relative to previous methods of pr…
Overlap junctions for high coherence superconducting qubits
X. Wu, J. L. Long, H. S. Ku +3
Fabrication of sub-micron Josephson junctions is demonstrated using standard processing techniques for high-coherence, superconducting qubits. These junctions are made in two separ…
Low-noise kinetic inductance traveling-wave amplifier using three-wave mixing
Michael R. Vissers, Robert P. Erickson, Hsiang-Sheng Ku +4
We have fabricated a wide-bandwidth, high dynamic range, low-noise cryogenic amplifier based on a superconducting kinetic inductance traveling-wave device. The device was made from…
Tunable coupling to a mechanical oscillator circuit using a coherent feedback network
Joseph Kerckhoff, Reed W. Andrews, H. S. Ku +4
We demonstrate a fully cryogenic microwave feedback network composed of modular superconducting devices connected by transmission lines and designed to control a mechanical oscilla…
