Floquet engineering of tight-binding Hamiltonians in momentum space lattices

D. Ronco, F. Arrouas, N. Ombredane +4

Quantum simulation with ultracold atoms provides a versatile platform to emulate condensed-matter models. In particular, momentum-space lattices enable the realization of programma…

Time-optimal force sensing with ultracold atoms

Nicolas Ombredane, Eloi Flament, Charles Babin +3

We develop a time-optimal approach to force sensing using a Bose-Einstein condensate in a shaken optical lattice. Optimal control protocols are derived from a Fisher information fr…

Unitary Transformations using Robust Optimal Control on a Cold Atom Qudit

E. Flament, N. Ombredane, F. Arrouas +4

In this paper, we design and experimentally implement various robust quantum unitary transformations (gates) acting on -dimensional vectors (qudits) by tuning a single control p…

Probing non-ergodicity and symmetry via coherent forward scattering in a shaken rotor

F. Arrouas, J. Hébraud, N. Ombredane +9

The Coherent Backscattering (CBS) peak is a well-known interferential signature of weak localization in disordered or chaotic systems. More recently, a second interference feature…

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…

A regular Hamiltonian halting ratchet for matter wave transport

N. Dupont, L. Gabardos, F. Arrouas +4

We report on the design of a Hamiltonian ratchet exploiting periodically at rest integrable trajectories in the phase space of a modulated periodic potential, leading to the linear…

Phase-space distributions of Bose-Einstein condensates in an optical lattice: Optimal shaping and reconstruction

N. Dupont, F. Arrouas, L. Gabardos +5

We apply quantum optimal control to shape the phase-space distribution of Bose-Einstein condensates in a one-dimensional optical lattice. By a time-dependent modulation of the latt…
