摘要：

The output noise temperature, rather than the standard input noise temperature, is the fundamental measure of the shot noise of the superconducting (SIS) quasiparticle mixer. This conclusion is based on extensive numerical computations of the properties of optimized SIS receivers and also on analytic calculations with separate consideration of correlated and uncorrelated noise sources. We predict T(receiver) = 2 x T(mixer) for many SIS receivers. Numerous experiments substantiate our analysis.
