Abstract

Utilizing the ultra-high sensitivity of a superconducting carbon nanotube (CNT) sensor to probe the quantum ground state is a promising approach. However, reproducible and reliable fabrication of such devices is still to be shown due to the demands on high temperature stable materials that the CNT growth requires and the crucial role the contact resistance plays for inducing superconductivity into the CNT. We approach the challenge with the molybdenum rhenium (MoRe) microwave cavity, which withstands high temperatures. Additionally we use a thin layer of palladium to improve contact resistance to the CNT. We conrm our measurements of the critical current through the Josephson junction with calculations.
