Description
The use of nanoscale structures to enhance local electric fields has seen much recent use in improving the effectiveness of numerous, optically-driven systems. As such, we investigate how these nanoscale enhancements can be used to improve the operation of quantum control systems. These nanoscale systems have various different effects on quantum systems, but in most cases are able to increase the local electric field and the spontaneous decay experienced by transitions in the system. The most noticeable property of these enhancements is that are strongly dependant on the position and quantization axis of the system relative to the arrangement of materials in the nanostructure.
With this in mind we investigate how this directional dependance can be exploited to improve the overall operation of quantum informations systems. We take advantage of non-symmetric structures and different driving field directions in order to selectively tune the environment of a quantum system. We also show that simple noble metal nanoparticles can arranged and used to rapidly prepare pure state qubits from arbitrary mixed states while retaining low decoherence during regular operations.
