Optimal control of a Bose-Eintein Condensate in an optical lattice: The non-linear and two-dimensional cases
E. Dionis, B. Peaudecerf, S. Guérin +2
We numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the…
Sub-Harmonic Control of a Fluxonium Qubit via a Purcell-Protected Flux Line
Johannes Schirk, Florian Wallner, Longxiang Huang +21
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demo…
Optimal Floquet Engineering for Large Scale Atom Interferometers
T. Rodzinka, E. Dionis, L. Calmels +6
The effective control of atomic coherence with cold atoms has made atom interferometry an essential tool for quantum sensors and precision measurements. The performance of these in…
Introduction to Theoretical and Experimental aspects of Quantum Optimal Control
Q. Ansel, E. Dionis, F. Arrouas +4
Quantum optimal control is a set of methods for designing time-varying electromagnetic fields to perform operations in quantum technologies. This tutorial paper introduces the basi…
Floquet operator engineering for quantum state stroboscopic stabilization
Floriane Arrouas, Lucas Gabardos, Nicolas Ombredane +6
Optimal control is a valuable tool for quantum simulation, allowing for the optimized preparation, manipulation, and measurement of quantum states. Through the optimization of a ti…
Optimal Control Strategies for Parameter Estimation of Quantum Systems
Quentin Ansel, Etienne Dionis, Dominique Sugny
Optimal control theory is an effective tool to improve parameter estimation of quantum systems. Different methods can be employed for the design of the control protocol. They can b…
Characterization of a driven two-level quantum system by Supervised Learning
R. Couturier, E. Dionis, S. Guérin +2
We investigate the extent to which a two-level quantum system subjected to an external time-dependent drive can be characterized by supervised learning. We apply this approach to t…
Time-optimal control of two-level quantum systems by piecewise constant pulses
E. Dionis, D. Sugny
We apply an extension of the Pontryagin Maximum Principle to derive time-optimal controls of two-level quantum systems by means of piecewise constant pulses. Global optimal solutio…
