Approaching the Quantum Limit in Axion Detection at IBS-CAPP and IBS-DMAG
We present the development of two complementary amplifier architectures for axion haloscope experiments, based on two types of Josephson Parametric Amplifiers (JPAs).The first employs a multi-chip module of flux-driven JPAs in a parallel-series configuration, enabling near quantum-limited amplification over an extended tunable range of between 1.2 and 1.5 GHz.The second design features a lumped-element JPA, offering continuous tunability across a wide frequency range from 2.4 to 4 GHz.Both approaches demonstrate near-quantum-limited noise performance and are compatible with operation in cryogenic environments.These amplifiers significantly enhance the sensitivity and frequency coverage of axion search experiments, and also provide new opportunities for broadband quantum sensing applications.
