Efficient sideband cooling protocol for long trapped-ion chains

J. -S. Chen, K. Wright, N. C. Pisenti +5

Trapped ions are a promising candidate for large scale quantum computation. Several systems have been built in both academic and industrial settings to implement modestly-sized qua…

Measurements of $^{27}$ Al $^{+}$ and $^{25}$ Mg $^{+}$ magnetic constants for improved ion clock accuracy

S. M. Brewer, J. -S. Chen, K. Beloy +14

We have measured the quadratic Zeeman coefficient for the $^{1} S_{0} \leftrightarrow^{3} P_{0}$ optical clock transition in $^{27}$ Al $^{+}$ , $C_{2} = - 71.944 (24)$ ~MHz/T $^{2}$ , an…

Sympathetic ground state cooling and time-dilation shifts in an $^{27} Al^{+}$ optical clock

J. -S. Chen, S. M. Brewer, C. W. Chou +3

We report on Raman sideband cooling of $^{25} Mg^{+}$ to sympathetically cool the secular modes of motion in a $^{25} Mg^{+}$ - $^{27} Al^{+}$ two-ion pair to near th…
