Tuning methods for semiconductor spin--qubits [PDF]

open access: yesPhys. Rev. Applied 10, 054026 (2018), 2018
We present efficient methods to reliably characterize and tune gate-defined semiconductor spin qubits. Our methods are designed to target the tuning procedures of semiconductor double quantum dot in GaAs heterostructures, but can easily be adapted to other quantum-dot-like qubit systems. These tuning procedures include the characterization of the inter-
