CONTROL OF QUANTUM SYSTEMS [PDF]

open access: yesInternational Journal of Modern Physics B, 2002
A quantum system subject to external fields is said to be controllable if these fields can be adjusted to guide the state vector to a desired destination in the state space of the system. Fundamental results on controllability are reviewed against the background of recent ideas and advances in two seemingly disparate endeavours: (i) laser control of ...
