Searching for quantum optimal controls under severe constraints
Gregory Riviello, Katharine Moore Tibbetts, Constantin Brif +4
The success of quantum optimal control for both experimental and theoretical objectives is connected to the topology of the corresponding control landscapes, which are free from lo…
Searching for quantum optimal controls in the presence of singular critical points
Gregory Riviello, Constantin Brif, Ruixing Long +4
Quantum optimal control has enjoyed wide success for a variety of theoretical and experimental objectives. These favorable results have been attributed to advantageous properties o…
Sampling-based Learning Control for Quantum Systems with Hamiltonian Uncertainties
Daoyi Dong, Chunlin Chen, Ruixing Long +2
Robust control design for quantum systems has been recognized as a key task in the development of practical quantum technology. In this paper, we present a systematic numerical met…
Sampling-based learning control of inhomogeneous quantum ensembles
Chunlin Chen, Daoyi Dong, Ruixing Long +2
Compensation for parameter dispersion is a significant challenge for control of inhomogeneous quantum ensembles. In this paper, we present a systematic methodology of sampling-base…
Time minimal trajectories for two-level quantum systems with two bounded controls
Ugo Boscain, Fredrik Grönberg, Long Ruixing +1
In this paper we consider the minimum time population transfer problem for a two level quantum system driven by {\em two} external fields with bounded amplitude. The controls are m…
Gradient flow for controlling quantum ensemble
Ruixing Long, Herschel Rabitz
We propose in this paper a gradient-type dynamical system to solve the problem of maximizing quantum observables for finite dimensional closed quantum ensembles governed by the con…
