Coherent and optimal control of adiabatic motion of ions in a trap
Meiyu Zhao, Dmitri Babikov · Physical Review A · 2008
Small anharmonicity, created along the axial direction of the trap, allows controlling the motional states of ions adiabatically using electric fields. In this paper several important aspects of this control scheme are explored theoretically. The pulses for various state transformations, including universal quantum gates, are derived using the optimal control theory. They exhibit simple shapes and other favorable properties, which indicate a promising route for practical implementation.
