A new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing can be based on the use of micro-fabricated optical elements. With these elements versatile and integrated atom optical devices can be created in a compact fashion. This approach opens the possibility to scale, parallelize, and miniaturize atom optics for investigations in fundamental research and application.
For the implementation of new approaches for quantum information processing, we use arrays of micro-lenses to create a two-dimensional system of atom samples in dipole traps that can serve as the carriers for the qubits. Micro-optical elements are also used to generate waveguides, beam splitters, and interferometer-type structures for guided atoms. These systems present the atom-optical equivalents to the respective structures in integrated light optics.
In the future, the application of micro-optics for the optical manipulation of atomic systems is expected to have a significant impact on quantum optics, quantum information processing, and matter wave optics. We report on the progress of our work.
