State-of-the-art technology in micro- and nano-fabrication can be combined with the quantum optical techniques of laser cooling, laser trapping, and quantum control to achieve efficient preparation of atomic quantum systems. Using optical micro-structures for this purpose allows us to create versatile trapping and guiding geometries with high flexibility.
Together with a significant degree of decoupling from the environment, this approach makes scalable systems for the investigation of quantum physics with neutral atoms accessible for experimental research. Potential studies range from fundamental questions of quantum physics, such as investigations of decoherence, to the application in quantum information processing and integrated atom optics.
We investigate the realization of small-scale quantum processors and atom optical systems for the coherent manipulation of atomic matter waves which are based on dipole potentials created by optical micro-structures.
