Universal control of quantum subspaces and subsystems
arXiv:quant-ph/0305013 · doi:10.1103/PhysRevA.69.022313
Abstract
We describe a broad dynamical-algebraic framework for analyzing the quantum control properties of a set of naturally available interactions. General conditions under which universal control is achieved over a set of subspaces/subsystems are found. All known physical examples of universal control on subspaces/systems are related to the framework developed here.
