Implementation of Quantum Gates via Optimal Control
Sonia Schirmer
Starting with the basic control system model often employed in NMR pulse design, we derive more realistic control system models taking into account effects such as off-resonant exc…
Analysis of Lyapunov Control for Hamiltonian Quantum Systems
Xiaoting Wang, Sonia Schirmer
We present detailed analysis of the convergence properties and effectiveness of Lyapunov control design for bilinear Hamiltonian quantum systems based on the application of LaSalle…
Physics-based mathematical models for quantum devices via experimental system identification
Sonia Schirmer, Daniel Oi, Simon Devitt
We consider the task of intrinsic control system identification for quantum devices. The problem of experimental determination of subspace confinement is considered, and simple gen…
Comparative Analysis of Control Strategies
Sonia G Schirmer, Peter J Pemberton-Ross, Xiaoting Wang
Different ways of modelling quantum control systems, formulating control problems and solving the resulting problems are considered and compared. In particular, we compare the perf…
Global controllability with a single local actuator
Sonia G. Schirmer, Ivan C. H. Pullen, Peter J. Pemberton-Ross
We show that we can achieve global density-operator controllability for most N-dimensional bilinear Hamiltonian control systems with general fixed couplings using a single, locally…
