Variable structure control of quantum systems
Wei Cui, Yu Liang Pan, Daoyi Dong · 2015
We prepare an arbitrary quantum state in the presence of noisy environment as well as systematic uncertainty using a variable structure control method involving quantum weak measurement. We first steer the quantum state to a sliding surface and then manipulate the state from the sliding surface to the target by quantum weak measurement. We demonstrate that both the two steps are robust against systematic and amplitude noises.
