Description
In this talk I will initially review the current capabilities of cryogenic HEMT based LNA technology; discussing the progress that has been made, how the technology has been applied and the experiments (including axion detection) that have become possible as the device noise temperature has progressed towards the quantum noise limit.
I will then outline a recently developed parametric amplification technology, that exploits the kinetic inductance of superconductors, and offers the possibility of quantum noise or even sub quantum noise limited amplification.
