Description
Quantum computers promise new ways of solving problems that are difficult for classical computers, but their practical realization requires extremely precise control of quantum systems. In this talk, I will introduce the general challenge of controlling quantum devices and explain why reliable quantum operations are essential for scalable quantum computing. I will then present a new approach for quantum optimal control that iteratively improves control parameters by evaluating how the implemented operation responds to applied control fields¹. Compared to conventional optimization strategies, the method avoids the need for hyperparameter tuning, making it more practical and accessible for real-world applications. Using the example of multi-qubit gate optimization, I will give an overview of how such control methods can help improve the fidelity and robustness of quantum operations.
