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…
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…
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…
Effective models for quantum optics with multilayer open cavities
Astghik Saharyan, Juan-Rafael Álvarez, Axel Kuhn +1
Effective models to describe the dynamics of an open cavity have been extensively discussed in the literature. In many of these models the cavity leakage to the outside is treated…
Optimal control and ultimate bounds of 1:2 nonlinear quantum systems
Jing-jun Zhu, Kaipeng Liu, Xi Chen +1
Using optimal control, we establish and link the ultimate bounds in time (referred to as quantum speed limit) and energy of two- and three-level quantum nonlinear systems which fea…
Propagating single photons from an open cavity: Description from universal quantization
Astghik Saharyan, Benjamin Rousseaux, Zsolt Kis +2
Over the last decades, quantum optics has evolved from high quality factor cavities in the early experiments toward new cavity designs involving leaky modes. Despite very reliable…
