Quantum degenerate potassium-rubidium mixtures

We report on the production of quantum degenerate mixtures of potassium and rubidium isotopes, by means of evaporative cooling in a magnetic trap. Specifically, we produce a Bose-Bose mixture With K-41 and Rb-87 and Fermi-Bose mixture With K-40 and Rb-87. Application of association schemes in these systems may allow the production of degenerate gases of heteronuclear molecules of both bosonic and fermionic character. Ultracold dipolar molecules have been recognized as a viable candidate for the implementation of quantum computing.
