Optical quantum control of localized spins in semiconductors

摘要

We discuss schemes for the realization of quantum information devices using optical techniques and the electronic and spin degrees of freedom of diluted impurities in semiconductors. State-of-the-art nano-optical techniques can address a single impurity localized in a semiconductor. The optical properties of the host can be used to efficiently control the internal degrees of freedom of the impurities, and therefore to encode and process quantum information.
