CALIBRATING MAJORANA QUBITS BY PROBING TOPOLOGICAL DEGENERACY

Abstract:

A method for use with a topological quantum computing device is provided. The method may include setting a plurality of device parameters for a qubit architecture including a plurality of Majorana zero modes (MZMs). The method may further include calibrating the plurality of device parameters at least in part by determining whether the plurality of MZMs exhibit ground state degeneracy. When the plurality of MZMs are determined to not exhibit ground state degeneracy, calibrating the plurality of device parameters may further include modifying one or more device parameters of the plurality of device parameters. When the plurality of MZMs are determined to exhibit ground state degeneracy, the method may further include modifying one or more parameters of a measurement device coupled to the qubit architecture.
