Hybrid quantum networks, multilayered superconducting structures. The subject of the research. Quantum transport in hybrid heterostructures based on nanoscale metal films with superconducting ordering; transmission of quantum information encoded in quasiparticle charges. The purpose of the research. Development and improvement of superconducting network components for processing and controlled transmission of quantum information encoded in the quantum state of quasiparticle excitations. Research methods. Charge scattering theory applied to complex heterostructures for calculations of transport characteristics of superconducting networks. The main results of the work. An original method for calculating transport characteristics of multilayered hybrid structures based on superconductors is proposed. A new approach for revealing topologically protected edge currents in quantum materials is proposed. The novel method is based on a modification of a scanning probe microscope with two tips, one of which is in the superconducting state, which significantly increases the sensitivity of the device to quantum correlations. The charge scattering formalism in superconducting heterostructures is generalized to the case of temporal processes and the time-dependent transport of wave packets through the elements of the superconducting network is analyzed. It is shown theoretically that the appropriate choice of the input wave packet allows to control the ratio of output charges using a phenomenological parameter. that sets a new energy scale in the wave packet. The effect of an inelastic interaction of quasiparticle excitations with external degrees of freedom (decoherence) on transport characteristics of hybrid systems is clarified.
