On extrema of the objective functional for short-time generation of single qubit quantum gates
Alexander Pechen, Nikolay Il'in
In the present work the extrema of the objective functional for the problem of generation of quantum gates (logical elements for quantum computations) for two--level systems are in…

Control landscape for ultrafast manipulation by a qubit
Alexander Pechen, Nikolay Il'in
In this work we study extrema of objective functionals for ultrafast manipulation by a qubit. Traps are extrema of the objective functionals which are optimal for manipulation by q…

Trap-free manipulation in the Landau-Zener system
Alexander Pechen, Nikolay Il'in
The analysis of traps, i.e., locally but not globally optimal controls, for quantum control systems has attracted a great interest in recent years. The central problem that has bee…
