Entropy production versus memory effects in two-level open quantum systems
Guillaume Théret, Dominique Sugny, Camille L. Latune
We compare several definitions of entropy production rate introduced in the literature from a large variety of situations and motivations, and then analyze their relations with mem…
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…
Application of the Pontryagin Maximum Principle to the robust time-optimal control of two-level quantum systems
O. Fresse-Colson, S. Guérin, Xi Chen +1
We study the time-optimal robust control of a two-level quantum system subjected to field inhomogeneities. We apply the Pontryagin Maximum Principle and we introduce a reduced spac…
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…
Energy shortcut of N-level quantum protocols by optimal control
C. L. Latune, M. B. Puthuveedu Shebeek, D. Sugny +1
We introduce an energetically-optimal method inspired from Shortcut-To-Adiabaticity (STA) processes, named Quantum-Optimal-Shortcut-To-Energetics (QOSTE). QOSTE produces the same t…
Characterization of P-divisibility in two-level open quantum systems
G. Théret, C. Lombard-Latune, D. Sugny
We study different characterizations of P-divisibility in two-level open quantum systems whose dynamics are governed by a time-local master equation with time-dependent relaxation…
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…
