The development of techniques for producing, trapping, and detecting ultracold polar molecules, including assembly of molecules from ultracold atoms and the direct cooling of both neutral and ionized molecules is the first theme of the project. The second is controlling the arising interactions using external electromagnetic fields, thus manipulating collisions and chemical reactions, and engineering molecule-based quantum information. The third is development of applications for ultracold polar molecules, such as technologies for high-resolution spectroscopy, engineering of highly-correlated interacting many-body systems. The outcome includes the first steps towards quantum-degenerate gases of polar molecules for a chemically diverse range of species, which have been trapped and cooled to the ultracold regime. Novel types of collisional and chemical-reactive behavior were observed, controlled, and understood theoretically. The first implementations of quantum information encoding and processing with polar molecule qubits were demonstrated, and improved schemes for large-scale systems are being devised. Novel features of many-body systems of strongly-interacting polar molecules were analyzed, and the details of molecular structure were measured and applied.
