For our newly formed theory division located in Toronto, Canada, we are seeking an excellent research scientist to work on various theoretical aspects of quantum computer design and development. This involves, but is not limited to, development of new photonic-based quantum computing architectures, implementation of quantum algorithms to be compatible with the ORCA photonic design and development of tailored fault-tolerant error correcting codes. An important milestone on the way to the photonic fault-tolerant universal quantum computer is a noisy near-term device with limited fault tolerance capabilities. The successful candidate is expected to contribute to its development in close collaboration with the ORCA quantum hardware group.

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.
