Independent optical control of co-located 85Rb and 87Rb ensembles for quantum information processing

Gregory Smail, Mark Bashkansky, Adam T. Black

Neutral atoms are widely used for quantum computing and quantum information applications due to their scalability and high-fidelity Rydberg interactions. Recently, dual-species single atom arrays have been demonstrated in which one species is used for computation and the other is used to perform auxiliary mid-circuit measurements. We propose the co-location of two ensembles of ultracold 85Rb and 87Rb in a crossed-beam optical dipole trap for quantum information applications. Due to the isotope shift, crosstalk between the ensembles is small and each ensemble can be addressed independently. The trapped ensembles can be made to support only a single collective Rydberg excitation while providing robustness against collisional losses. We present progress towards the independent control of two Rb ensembles co-located in a dual-species crossed beam optical dipole trap and discuss measurements of the crosstalk between the ensembles.

Dual-Species Quantum Degeneracy of 40K and 87Rb on an Atom Chip

M. Extavour, Lindsay J. LeBlanc, Thorsten Schumm +5 more

In this article we review our recent experiments with a 40K‐87Rb mixture. We demonstrate rapid sympathetic cooling of a 40K‐87Rb mixture to dual quantum degeneracy on an atom chip. We also provide details on efficient BEC production, species‐selective magnetic confinement, and progress toward integration of an optical lattice with an atom chip. The efficiency of our evaporation allows us to reach dual degeneracy after just 6 s of evaporation ‐ more rapidly than in conventional magnetic traps. When optimizing evaporative cooling for efficient evaporation of 87Rb alone we achieve BEC after just 4 s of evaporation and an 8 s total cycle time.
