In this paper we will describe the characterisation of a rf amplification chain based on a travelling wave parametric amplifier (TWPA). The detection chain is meant to be used for dark matter axion searches and thus it is mounted coupled to a high Q microwave resonant cavity. A system noise temperature T sys = (3 . 3 ± 0 . 1) K has been measured at a frequency of 10.77 GHz, using a novel scheme allowing measurement of T sys exactly at the cavity output port.

Widely tunable, nondegenerate three-wave mixing microwave device operating near the quantum limit.
TLDR
The unprecedented accuracy with which the crossover between zero-point fluctuations and shot noise has been measured provides an upper bound for the noise and dissipation intrinsic to the device.
Observation of 4.2-K equilibrium-noise squeezing via a Josephson-parametric amplifier.

SQUID-based microwave cavity search for dark-matter axions.
TLDR
The first result from such an axion search using a superconducting first-stage amplifier (SQUID) replacing a conventional GaAs field-effect transistor amplifier is reported, setting the stage for a definitive axions search utilizing near quantum-limited SQUID amplifiers.
Axion Search with a Quantum-Limited Ferromagnetic Haloscope.
TLDR
The scientific run of the ferromagnetic axion haloscope resulted in the best limit on dark matter axions to electron coupling constant in a frequency span of about 120 MHz, corresponding to the axion-mass range 42.4-43.1  μeV.
