Progress toward scalable quantum information processing using $^{6}$Li and $^{133}$Cs atoms

We present our progress on the construction of a novel, scalable quantum information processing system. The system consists of both fermionic $^6$Li and bosonic $^{133}$Cs atoms. The two species are simultaneously and independently trapped in two separate optical lattices. $^6$Li atoms are cooled into a degenerate band-insulator state that will allow uniform loading of one atom per site. These $^6$Li atoms serve as quantum bits (qubits). $^{133}$Cs atoms have a lower filling of one atom per 100 sites and will serve as messengers to induce entanglement among the qubits. In order to implement collision-based entangling operations, our plan for initial studies include the interspecies collision properties of $^{133}$Cs-$^6$Li at a magnetic field of up to 1000G, and the control of atoms on the single-atom level in two-color optical lattices.
