Description

Resolved sideband cooling provides an important technique in preparing the trapped ions to their motional ground state, which is essential in ion-based quantum computation. Here we present a surpassing sideband cooling performance in trapped ions utilizing light-mediated dipole-dipole interactions among them. By placing the ions at magic interparticle distances, we find that the target ion can be cooled closer to the zero-phonon state, outperforming the single-ion limit. We further investigate the effect of different ionic configurations, number of ions, and laser detuning, where we identify various optimal parameter regimes in superior cooling performance. Our results provide insights to cooling ions with collective dipole-dipole interactions and pave the way toward implementing genuine quantum operations in multiple quantum registers.
