Optimal control of a Bose-Eintein Condensate in an optical lattice: The non-linear and the two-dimensional cases

Autor: Dionis, E., Peaudecerf, B., Guérin, S., Guéry-Odelin, D., Sugny, D.

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 non-linear case and for a two-dimensional lattice. We show how to cons

Optimal Floquet Engineering for Large Scale Atom Interferometers

Autor: Rodzinka, T., Dionis, E., Calmels, L., Beldjoudi, S., Béguin, A., Guéry-Odelin, D., Allard, B., Sugny, D., Gauguet, A.

Publikováno v: Nat Commun 15, 10281 (2024)

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 interferometers is closely related to the operation of large wave packet

Autor: Ansel, Q., Dionis, E., Arrouas, F., Peaudecerf, B., Guérin, S., Guéry-Odelin, D., Sugny, D.

Publikováno v: J. Phys. B 57, 133001 (2024)

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 basic elements of this theory based on the Pontryagin maximum principle, i

Characterization of a driven two-level quantum system by Supervised Learning

Autor: Couturier, R., Dionis, E., Guérin, S., Guyeux, C., Sugny, D.

Publikováno v: Entropy 25, 446 (2023)

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 the case of bang-bang control and the estimation of the offset and the

Time-optimal control of two-level quantum systems by piecewise constant pulses

Autor: Dionis, E., Sugny, D.

Publikováno v: Phys. Rev. A 107, 032613 (2023)

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 solutions are obtained for state-to-state transfer in the cases with one and
