Quantum simulators are coherently controlled quantum systems used to simulate other quantum systems. Based on Feynman's vision of efficient simulation of one quantum system using another, quantum simulators hold promise for tackling problems in quantum many-body physics hitherto intractable on classical computers and exploring new physical phenomena.

Interacting Bose-Bose or Bose-Fermi mixtures can give access to a wealth of physical phenomena which go beyond those accessible with purely bosonic or fermionic systems. Both the bosonic and fermionic atomic species can be simultaneously cooled down to very low temperatures of around a few tens of nK to reach the quantum regime. The physics of Bose-Bose and Bose-Fermi mixtures in periodic optical potentials is extremely rich and yet to be fully understood.

In our experiment, we cool and trap Sodium and Potassium to ultra-cold temperatures to realise quantum mixtures for Quantum Simulation using ultra-cold quantum gases in optical lattices and disordered potentials.
