Analyzing and Unifying Robustness Measures for Excitation Transfer Control in Spin Networks
S. P. O'Neil, I. Khalid, A. A. Rompokos +4
Recent achievements in quantum control have resulted in advanced techniques for designing controllers for applications in quantum communication, computing, and sensing. However, th…
Time Domain Sensitivity of the Tracking Error
S. O'Neil, S. G. Schirmer, F. C. Langbein +2
A strictly time-domain formulation of the log-sensitivity of the error signal to structured plant uncertainty is presented and analyzed through simple but representative classical…
Applying classical control techniques to quantum systems: entanglement versus stability margin and other limitations
C. A. Weidner, S. G. Schirmer, F. C. Langbein +1
Development of robust quantum control has been challenging and there are numerous obstacles to applying classical robust control to quantum system including bilinearity, marginal s…
Robustness of Quantum Systems Subject to Decoherence: Structured Singular Value Analysis?
S G Schirmer, F C Langbein, C A Weidner +1
We study the problem of robust performance of quantum systems under structured uncertainties. A specific feature of closed (Hamiltonian) quantum systems is that their poles lie on…
Reinforcement Learning vs. Gradient-Based Optimisation for Robust Energy Landscape Control of Spin-1/2 Quantum Networks
I. Khalid, C. A. Weidner, E. A. Jonckheere +2
We explore the use of policy gradient methods in reinforcement learning for quantum control via energy landscape shaping of XX-Heisenberg spin chains in a model agnostic fashion. T…
Analysis of Lyapunov Method for Control of Quantum States
Xiaoting Wang, Sonia Schirmer
The natural trajectory tracking problem is studied for generic quantum states represented by density operators. A control design based on the Hilbert-Schmidt distance as a Lyapunov…
