Selective and Robust Time-Optimal Rotations of Spin Systems
Quentin Ansel, Steffen J. Glaser, Dominique Sugny
We study the selective and robust time-optimal rotation control of several spin-1/2 particles with different offset terms. For that purpose, the Pontryagin Maximum Principle is app…
Introduction to the Pontryagin Maximum Principle for Quantum Optimal Control
U. Boscain, M. Sigalotti, D. Sugny
Optimal Control Theory is a powerful mathematical tool, which has known a rapid development since the 1950s, mainly for engineering applications. More recently, it has become a wid…
Robust control of an ensemble of springs: Application to Ion Cyclotron Resonance and two-level Quantum Systems
V. Martikyan, A. Devra, D. Guéry-Odelin +2
We study the simultaneous control of an ensemble of springs with different frequencies by means of adiabatic, shortcut to adiabaticity and optimal processes. The linearity of the s…
Purity Speed Limit of Open Quantum Systems from Magic Subspaces
A. A. Diaz V., V. Martikyan, S. J. Glaser +1
We introduce the concept of Magic Subspaces for the control of dissipative N- level quantum systems whose dynamics are governed by Lindblad equation. For a given purity, these subs…
Fundamental Bounds on Qubit Reset
Daniel Basilewitsch, Jonas Fischer, Daniel M. Reich +2
Qubit reset is a basic prerequisite for operating quantum devices, requiring the export of entropy. The fastest and most accurate way to reset a qubit is obtained by coupling the q…
