• Abstract: Hybrid quantum systems that unite laser-cooled trapped ions and ultracold quantum gases in a single experimental setup have opened a rapidly advancing field of study, including Quantum chemistry, polaron physics, quantum information processing and quantum simulations. We present a fully developed and tested ion trap chip and propose a flat chip trap that can be placed beneath the ion trap. This design substantially addresses the difficulties specific to hybrid traps and features well-aligned chips that allow for independent adjustment of the depth of the atomic trap and the confinement and positioning of ions. The ion trap has been successfully tested with linear ion crystals of Yb$^{+}$ and neutral $^{87}$Rb were also loaded into a mMOT a few millimeters under the ion trapping region.

  Trapped-ion quantum information processing may benefit from qubits encoded in isotopes that are practically available in only small quantities. Laser ablation provides a method of controllably liberating neutral atoms or ions from low-volume targets. Here we investigate ablation-based ion loading into surface-electrode traps of different sizes to test a model describing ion loading probability.

  We show how to implant low-energy ions into silicon devices featuring an enlarged 60x60 $mu$m sensitive area. Despite the weak internal electric field, near-unity charge collection efficiency is obtained from the entire sensitive area. This can be explained by the critical role that the high-quality thermal gate oxide plays in the ion detection response.

  We introduce a novel algorithmic cooling protocol for transferring phonons from poorly- to efficiently-cooled modes. We demonstrate it experimentally by simultaneously bringing two motional modes of a Be$+$-Ar$13+$ mixed Coulomb crystal close to their zero-point energies. We reach the lowest temperature reported for a highly charged ion, with a residual temperature of only $Tlesssim200mathrmmu K$ in each of the two modes.

Here we report the design and the simulation of a novel ion trapping setup especially conceived for the integration with an ultracold atoms experiment.
