In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin ...
Maser emissions, "cosmic lasers" from interstellar and circumstellar medium, are produced by the amplification of stimulated emissions. Bright and compact maser sources are good targets for high-accuracy astrometry in the ...
