Robust control of linear systems and shortcut to adiabaticity based on superoscillations
Qi Zhang, Xi Chen, David Guéry-Odelin
With the advent of quantum technologies, control issues are becoming increasingly important. In this article, we address the control in phase space under a global constraint provid…
Time scaling and quantum speed limit in non-Hermitian Hamiltonians
F. Impens, F. M. D'Angelis, F. A. Pinheiro +1
We report on a time scaling technique to enhance the performances of quantum protocols in non-Hermitian systems. The considered time scaling involves no extra-couplings and yields…
Connection between inverse engineering and optimal control in shortcuts to adiabaticity
Qi Zhang, Xi Chen, David Guéry-Odelin
We consider fast high-fidelity quantum control by using a shortcut to adiabaticity (STA) technique and optimal control theory (OCT). Three specific examples, including expansion of…
Chaos-Assisted Long-Range Tunneling for Quantum Simulation
Maxime Martinez, Olivier Giraud, Denis Ullmo +4
We present an extension of the chaos-assisted tunneling mechanism to spatially periodic lattice systems. We demonstrate that driving such lattice systems in an intermediate regime…
Fast and robust quantum state transfer in a topological Su-Schrieffer-Heeger chain with Next-to-Nearest-Neighbour interactions
Felippo M. D'Angelis, Felipe A. Pinheiro, David Guéry-Odelin +2
We suggest a method for fast and robust quantum-state transfer in a Su-Schrieffer-Heeger (SSH) chain, which exploits the use of next-to-nearest-neighbour (NNN) interactions. The pr…
Fast manipulation of Bose-Einstein condensates with an atom chip
R. Corgier, S. Amri, W. Herr +6
We present a detailed theoretical analysis of the implementation of shortcut-to-adiabaticity protocols for the fast transport of neutral atoms with atom chips. The objective is to…
Shortcuts to adiabaticity for an ion in a rotating radially-tight trap
M. Palmero, Shuo Wang, D. Guéry-Odelin +2
We engineer the fast rotation of a quantum particle confined in an effectively one-dimensional, harmonic trap, for a predetermined rotation angle and time, avoiding final excitatio…
Spin Wave Diffraction Control and Read-out with a Quantum Memory for Light
Gabriel Hétet, David Guéry-Odelin
A scheme for control and read-out of diffracted spins waves to propagating light fields is presented. Diffraction is obtained via sinusoidally varying lights shifts and ideal one-t…
Doubly resonant ultrachirped pulses
S. Ibáñez, A. Peralta Conde, D. Guéry-Odelin +1
Ultrachirped pulses for which the frequency chirp is of the order of the transition frequency of a two-level atom are examined. When the chirp is large enough, the resonance may be…
