In some practical applications, devices based on superconducting electronics, due to their unique set of parameters, are far superior to those based on conventional technologies, being in some cases the only viable option. One of the most advanced areas is the development of ultra-sensitive terahertz-range receivers: their operating frequency has reached 1 THz, and the noise temperature is only limited by quantum or photon noise.
