abstract = {We present efficient methods to reliably characterize and
tune gate-defined semiconductor spin qubits. Our methods are
developed for double quantum dots in GaAs heterostructures,
but they can easily be adapted to other quantum-dot-based
qubit systems. These tuning procedures include the
characterization of the interdot tunnel coupling, the tunnel
coupling to the surrounding leads, and the identification of
various fast initialization points for the operation of the
qubit. Since semiconductor-based spin qubits are compatible
with standard semiconductor process technology and hence
promise good prospects of scalability, the challenge of
efficiently tuning the dot’s parameters will only grow in
the near future, once the multiqubit stage is reached. With
the anticipation of being used as the basis for future
automated tuning protocols, all measurements presented here
are fast-to-execute and easy-to-analyze characterization
methods. They result in quantitative measures of the
relevant qubit parameters within a couple of seconds and
require almost no human interference.},
