Interest in superconducting microresonators has grown dramatically over the past decade.
Resonator performance has improved substantially through the use of improved geometries …

We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual
design and science program. This haloscope plans to search for bosonic dark matter across …

This paper reviews the state of rapidly emerging terahertz hot-electron nanobolometers
(nano-HEB), which are currently among of the most sensitive radiation power detectors at …

An ideal amplifier has very low noise, operates over a broad frequency range, and has large
dynamic range. Unfortunately, it is difficult to obtain all of these characteristics …

Superconducting qubits are electronic circuits comprising lithographically defined
Josephson tunnel junctions, inductors, capacitors, and interconnects. When cooled to …

Superconducting high kinetic inductance elements constitute a valuable resource for
quantum circuit design and millimeter-wave detection. Granular aluminum (grAl) in the …

Three-dimensional microwave cavities have recently been combined with superconducting
qubits in the circuit quantum electrodynamics architecture. These cavities should have less …

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 …

We present the design, construction, and commissioning results of ARCONS, the Array
Camera for Optical to Near-IR Spectrophotometry. ARCONS is the first ground-based …

Thin films of TiN were sputter-deposited onto Si and sapphire wafers with and without SiN
buffer layers. The films were fabricated into rf coplanar waveguide resonators, and internal …
