Probing the Weak-Driving Quantum Speed Limit via Drift-Aware Shooting Methods
Denis Janković, Saba Taherpour, Paul-Louis Etienney +2
A central goal of quantum optimal control is to achieve high-fidelity and low-energy control pulses. When quantum optimal control methods optimize every point of a pulse discretize…
Implementation of a shooting technique for quantum optimal control on spin qudits
Paul-Louis Etienney, Denis Janković, Killian Lutz +3
High-fidelity quantum control is a cornerstone of scalable quantum technologies. We introduce a shooting-based optimization framework that generates smooth, experimentally realisti…
Overcoming limitations on gate fidelity in noisy static exchange-coupled surface qubits
Hoang-Anh Le, Saba Taherpour, Denis Janković +1
Recent experiments demonstrated that the spin state of individual atoms on surfaces can be quantum-coherently controlled through all-electric electron spin resonance. By constructi…
Quantum Optimal Control Using MAGICARP: Combining Pontryagin's Maximum Principle and Gradient Ascent
Denis Janković, Jean-Gabriel Hartmann, Paul-Louis Etienney +3
We introduce the MAGICARP algorithm, a numerical optimization method for quantum optimal control problems that combines the structure provided by Pontryagin's Maximum Principle (PM…
