Abstract: 

Our research group is developing spin qubits in two drastically different semiconductors,
namely gallium arsenide and silicon. I will introduce the similarities and differences
between these material systems and explain why gate-defined quantum dots are an
attractive platform to develop spin-based quantum computers. Going from few-qubit
devices to larger quantum-dot arrays, the utilization of massive qubit fabrication in
microelectronics foundries becomes increasingly important for us. However, manual
device characterization at millikelvin temperatures is time consuming and expensive. I
will show our recent efforts to use active-learning approaches and FPGA-based real-time
estimation to characterize quantum dots and spin qubits with minimal human input.
