Optimal Control Strategies for Parameter Estimation of Quantum Systems
Quentin Ansel, Etienne Dionis, Dominique Sugny
Optimal control theory is an effective tool to improve parameter estimation of quantum systems. Different methods can be employed for the design of the control protocol. They can b…
Enhancing quantum exchanges between two oscillators
Quentin Ansel, Alexei D. Chepelianskii, Jose Lages
We explore the extent to which two quantum oscillators can exchange their quantum states efficiently through a three-level system which can be spin levels of colored centers in sol…
Optimal control and selectivity of qubits in contact with a structured environment
Quentin Ansel, Jonas Fischer, Dominique Sugny +1
We present a theoretical study of the optimal control of a qubit interacting with a structured environment. We consider a model system in which the bath is a bosonic reservoir at z…
Exploring the limits of the generation of non-classical states of spins coupled to a cavity by optimal control
Quentin Ansel, Dominique Sugny, Bruno Bellomo
We investigate the generation of non-classical states of spins coupled to a common cavity by means of a collective driving of the spins. We propose a control strategy using specifi…
Time-optimal selective pulses of two uncoupled spin 1/2 particles
L. Van Damme, Q. Ansel, S. J. Glaser +1
We investigate the time-optimal solution of the selective control of two uncoupled spin 1/2 particles. Using the Pontryagin Maximum Principle, we derive the global time-optimal pul…
Optimal control of an inhomogeneous spin ensemble coupled to a cavity
Q. Ansel, S. Probst, P. Bertet +2
We apply optimal control techniques to an inhomogeneous spin ensemble coupled to a cavity. A general procedure is proposed for designing the control strategies. We numerically show…
Optimizing fingerprinting experiments for parameter identification: Application to spin systems
Q. Ansel, M. Tesch, S. J. Glaser +1
We introduce the Optimal Fingerprinting Process which is aimed at accurately identifying the parameters which characterize the dynamics of a physical system. A database is first bu…
Robust optimal control of two-level quantum systems
L. Van Damme, Q. Ansel, S. J. Glaser +1
We investigate the time and the energy minimum optimal solutions for the robust control of two-level quantum systems against offset or control field uncertainties. Using the Pontry…
