As the field of superconducting quantum computing advances, the requirements for fabrication and materials has significantly clarified. In particular, this involves designing low temperature, low loss circuits with good RF properties. Specific categories that need to be addressed are intrinsic capacitive losses due to parasitic capacitive losses, unwanted modes in ground planes and RF losses in normal metal components. In this talk we will touch on each of these three areas by describing developments in superconducting films with optimized interfaces and novel junctions to avoid two level systems in amorphous materials, fabrication of self-aligned ground plane cross-overs, and new types of superconductors that can be integrated into the support circuitry of the superconducting devices.
