- Abstract
- <jats:title>Abstract</jats:title> <jats:p>We present a method for measuring the polarizability of Rydberg ions confined in the harmonic potential of a Paul trap. For a highly excited electronic state, the coupling between the electronic wave function and the trapping field modifies the excitation spectra depending on the motional state of the ion. This interaction strongly depends on the polarizability of the excited state and manifests itself in the state-dependent secular frequencies of the ion. We initialize a single trapped <jats:sup>40</jats:sup>Ca<jats:sup>+</jats:sup> ion from the motional ground state into coherent states with <jats:inline-formula> <jats:tex-math><?CDATA $|\alpha|$?></jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:mo>|</mml:mo> </mml:mrow> <mml:mi>α</mml:mi> <mml:mrow> <mml:mo>|</mml:mo> </mml:mrow> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="njpacbf06ieqn1.gif" xlink:type="simple" /> </jats:inline-formula> up to 12 using electric voltages on the trap segments.

By analysing the obtained spectra we extract the polarizability of Rydberg states which agree with numerical calculations. The method is applicable to different Rydberg states regardless of their principal or angular quantum numbers. An accurate value of the state polarizability is needed for quantum gate operations with Rydberg ion crystals.</jats:p>
