Summary: | A method of evaluating a semiconductor-superconductor heterojunction in a qubit register for a topological quantum computer includes: measuring a radio frequency (RF) junction admittance of the semiconductor-superconductor heterojunction to obtain mapping data; finding one or more regions of a parametric space consistent with a complete topology of the semiconductor-superconductor heterojunction by analysis of the mapping data; measuring a sub-RF conductance, including a non-local conductance of the semiconductor-superconductor heterojunction, in each of the one or more regions of the parametric space to obtain refined data; and searching for a boundary of the complete topological phase in the parametric space and a topological gap of the semiconductor-superconductor heterojunction for at least one of the one or more regions of the parametric space by analysis of the refined data.
