Recent advances in our ability to generate and manipulate quantum-coherent matterwaves is now ushering in a new era of quantum optics, where the roles of matter and light are almost exactly reversed. We are starting to be able to create almost arbitrary matterwave-images, (de)magnify, and project them. Matterwave mirrors, lenses and cavities are rapidly becoming reality. We have recently even been able to demonstrate a coherent waveguide for matterwaves.
In the nanoLace project, we are going to build a novel type of matterwave lithography experiment, where we will exploit the fact that time-dependent matterwave lenses will enable us to reduce the wavelength of matterwaves by orders of magnitude. We expect to be able to generate arbitrary patterns as small as a few nanometres. Potential applications stretch from the fundamental (quantum-matterwave-optics) to the industrial (micro-chip production with nanometric structures). To this end we are now in the process of setting up a novel matterwave lithography machine based on Bose-Einstein Condensates. The project is fully financed in the framework of the EU Future and Emerging Technologies (FET) network nanoLace.
