Comparative analysis of control strategies
Sonia Schirmer, Peter 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 performance of geometric and optimal control,
as well as iterative techniques for optimal control design versus direct optimization of a Lyapunov-type potential function for two problems of general interest: global control of qubits and entanglement generation in the form of Bell state preparation.
