Physics considered here is the active control of a quantum system and of its decoherence by its environment. The relevance is in the quantum nature of nanoscience and how coherent optics in semiconductor quantum dots can contribute to quantum control. This article reviews: (1) The more recent theory of control of a set of dot spins through cavity quantum electrodynamics and (2) the quantum basis for control of decoherence of the electron spin interacting with the nuclei in the quantum dot.
