Enhancing the controllability of quantum systems via a static field

Résumé

We provide a sufficient condition for the controllability of a bilinear closed quantum system based on the notion of static field and weakly conically connected spectrum. More precisely, we show that if a controlled Hamiltonian with two inputs has a weakly conically connected spectrum, then, freezing one of the two inputs at almost every constant value, the obtained single-input system is controllable. The result is illustrated with two examples, enantiomer-selective excitation in a chiral molecule and the driven Jaynes–Cummings Hamiltonian.
