Title: Enhanced ion-cavity coupling through cavity cooling in the strong coupling regime
Authors: Costas Christoforou, Corentin Pignot, Ezra Kassa, Hiroki Takahashi, Matthias Keller
Abstract summary: In this paper we demonstrate how cavity cooling can be implemented to improve the localisation of the ion. We obtain an enhanced ion-cavity coupling of $2pi times (16.7pm 0.1)$ MHz, compared with $2pi times (15.2pm 0.1)$ MHz when using only Doppler cooling.

Abstract: Incorporating optical cavities in ion traps is becoming increasingly important in the development of photonic quantum networks. However, the presence of the cavity can hamper efficient laser cooling of ions because of geometric constraints that the cavity imposes and an unfavourable Purcell effect that can modify the cooling dynamics substantially. On the other hand the coupling of the ion to the cavity can also be exploited to provide a mechanism to efficiently cool the ion. In this paper we demonstrate experimentally how cavity cooling can be implemented to improve the localisation of the ion and thus its coupling to the cavity. By using cavity cooling we obtain an enhanced ion-cavity coupling of $2\pi \times (16.7\pm 0.1)$ MHz, compared with $2\pi \times (15.2\pm 0.1)$ MHz when using only Doppler cooling.

Phonon-mediated quantum gates in trapped ions coupled to an ultracold atomic gas [0.0]
We study the dynamics of phonon-mediated qubit-qubit interactions between trapped ions in the presence of an ultracold atomic gas. tuning the atom-ion scattering length allows to tune the cooling rate of the ions. The system may also be used for quantum-enhanced measurements of the atom-ion interactions or properties of the atomic bath.

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.
