We demonstrate microwave kinetic inductance detectors (MKIDs) whose sensitivity is limited by photon noise at 50 mHz signal frequencies. The sub-Hz part of the detection spectrum is important for millimeter-wave instruments, yet photon noise below 1

Kinetic inductance traveling-wave parametric amplifiers (KITs) are under development for the read out of large cryogenic detector arrays. We present new KIT designs based on 20nm NbTiN films patterned by use of standard optical photolithography. We r

We present a theoretical model and experimental characterization of a microwave kinetic inductance traveling-wave amplifier (KIT), whose noise performance, measured by a shot-noise tunnel junction (SNTJ), approaches the quantum limit. Biased with a d

In dark matter axion searches, quantum uncertainty manifests as a fundamental noise source, limiting the measurement of the quadrature observables used for detection. We use vacuum squeezing to circumvent the quantum limit in a search for a new parti

We describe a dark matter axion detector designed, constructed, and operated both as an innovation platform for new cavity and amplifier technologies and as a data pathfinder in the 5–25 GHz range ( ∼ 20 – 100 μ eV ) . The platform is small bu

We present a superconducting microresonator thermometer based on two-level systems (TLS) that is drop-in compatible with cryogenic microwave systems. The operational temperature range is 50-1000~mK (which may be extended to 5~mK), and the sensitivity

Many experiments that interrogate fundamental theories require detectors whose sensitivities are limited by the laws of quantum mechanics. In cavity-based searches for axionic dark matter, vacuum fluctuations in the two quadratures of the cavity elec
