Qubit Control and Measurement Solutions
Bruno Küng, Prof. Stefan Filipp (Technical University of Munich and Walther-Meißner Institute) and Max Werninghaus (Technical University of Munich) look at how the growing effort towards large-scale superconducting quantum computers calls for instruments giving access to established methods for qubit control and measurement with as little engineering overhead as possible. Prof. Filipp covers the basics of superconducting quantum computing, including recent advances in optimal control methods for maximizing qubit gate fidelity. Bruno presents how to design and operate a qubit control setup at microwave frequencies with a simple Python interface controlling the measurement instruments; Max Werninghaus carries out a hands-on demonstration of this setup on a real qubit.
