In view of high-speed application of microwave transmission lines the coherent quantum effects in conducting components of transmission lines were considered. When a characteristic coherence length of the electronic wave functions becomes to be comparable with a length of the transmission line, such quantum effects make it necessary to consider the line as a “quantum” transmission line. We discuss a kind of such quantum effects related to the Einstein- Podolsky-Rosen paradox and analyze their influence on the properties of transmission lines and a possibility to increase a speed of signal transmission by using these quantum properties. Brief review of alternatives and phenomena related to the problem of Einstein-Podolsky-Rosen paradox is presented. On the example of the magnetic perturbation traveling in a closed superconducting microwave slotline the features of the quantum-mechanical reaction of this completely coherent macroscopic system in response to the local impact excitation of its part is considered. The transient processes are analyzed in the context of the Einstein-Rosen-Podolsky paradox.
