Abstract
- We achieve the sympathetic sideband cooling of a <superscript>40</superscript>Ca<superscript>+</superscript>–<superscript>27</superscript>Al<superscript>+</superscript> pair. Both axial modes of the two-ion chain are cooled simultaneously to near the ground state of the motion. The center of mass mode is cooled to an average phonon number of 0.052(9), and the breathing mode is cooled to 0.035(6). The heating rates of both a single <superscript>40</superscript>Ca<superscript>+</superscript> and the <superscript>40</superscript>Ca<superscript>+</superscript>–<superscript>27</superscript>Al<superscript>+</superscript> pair are measured and compared. This work is a fundamental step toward the implementation of a <superscript>40</superscript>Ca<superscript>+</superscript>–<superscript>27</superscript>Al<superscript>+</superscript> quantum logic clock.
