Flexible superconducting circuit

Abstract

The invention relates to a flexible superconducting circuit. The flexible superconducting circuit comprises in this order a first substrate, a first superconducting layer at a first side of the first substrate, a first normal conducting layer and a second superconducting layer. This arrangement provides a reduced resistance and reduced signal loss for high frequency signals through the superconducting circuit at temperatures below the critical temperature, while still allowing for testing at temperatures above the critical temperature of the first and second superconducting layers.
