Quantum Optimal Control Using MAGICARP: Combining Pontryagin's Maximum Principle and Gradient Ascent
Denis JankoviÄ, 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…
Probing the Weak-Driving Quantum Speed Limit via Drift-Aware Shooting Methods
Denis JankoviÄ, 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 JankoviÄ, 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…
A posteriori error estimates for the Lindblad master equation
Paul-Louis Etienney, Rémi Robin, Pierre Rouchon
We are interested in the simulation of open quantum systems governed by the Lindblad master equation in an infinite-dimensional Hilbert space. To simulate the solution of this equa…
