Control of non-controllable quantum systems: A quantum control algorithm based on Grover iteration
Zhang, C B, Dong, D Y, Chen, Z H · CERN Document Server (European Organization for Nuclear Research) · 2005
A new notion of controllability, eigenstate controllability, is defined for finite-dimensional bilinear quantum mechanical systems which are neither strongly completely controllably nor completely controllable. And a quantum control algorithm based on Grover iteration is designed to perform a quantum control task of steering a system, which is eigenstate controllable but may not be (strongly) completely controllable, from an arbitrary state to a target state.
