1. A traveling wave superconducting parametric amplifier comprising a chain of superconducting elements having a nonlinear kinetic inductance connected in series, said superconducting elements being deposited on a substrate, characterized in that traveling wave superconducting parametric amplifier it further comprises a dielectric layer of sub-micrometer thickness deposited on the substrate and covering said superconducting elements, and a conductive layer forming a ground plane deposited on top of the dielectric layer, the superconducting elements and the ground plane forming a microstrip-type transmission line.
