Exploring the Fidelity of Flux Qubit Measurement in Different Bases via the Quantum Flux Parametron
Yanjun Ji, Susanna Kirchhoff, Frank K. Wilhelm
High-fidelity qubit readout is a fundamental requirement for practical quantum computing systems. In this work, we investigate methods to enhance the measurement fidelity of flux q…
Correction Formulas for the Mølmer-Sørensen Gate Under Strong Driving
Susanna Kirchhoff, Frank K. Wilhelm, Felix Motzoi
The Mølmer-Sørensen gate is a widely used entangling gate for ion platforms with inherent robustness to trap heating. The gate performance is limited by coherent errors, arising fr…
An introduction into optimal control for quantum technologies
Frank K. Wilhelm, Susanna Kirchhoff, Shai Machnes +2
In this series of lectures, we would like to introduce the audience to quantum optimal control. The first lecture will cover basic ideas and principles of optimal control with the…
Optimized cross-resonance gate for coupled transmon systems
Susanna Kirchhoff, Torsten Keßler, Per J. Liebermann +4
The cross-resonant gate is an entangling gate for fixed frequency superconducting qubits introduced for untunable qubits. While being simple and extensible, it suffers from long du…
