State Manipulation in Decoherence‐Free Subspace
Shuang Cong · 2014
n the study of state manipulation in the decoherence-free subspaces in this chapter the construction of decoherence-free subspaces which contain the desired target state is presented first. The Lyapunov-based method for the interaction picture is then designed. Three simulation experiments are implemented in a three-level -type quantum system, a four-level energy open quantum system, and a Λ-type N-level atomic system. We also analyses the largest invariant set, the sufficient condition, and the construction of P via Schmidt orthogonalization.
