Versatile ytterbium ion trap experiment for operation of scalable ion-trap chips with motional heating and transition-frequency measurements

We present the design and operation of an ytterbium ion trap experiment with a setup offering versatile optical access and 90 electrical interconnects that can host advanced surface and multilayer ion trap chips mounted on chip carriers. We operate a macroscopic ion trap compatible with this chip carrier design and characterize its performance, demonstrating secular frequencies $>$1 MHz, and trap and cool nearly all of the stable isotopes, including ¹⁷¹Yb{}⁺$ ions, as well as ion crystals. For this particular trap we measure the motional heating rate ${}{n ̇ \.{}{}}{}$ and observe an ${}{n ̇ \.{}{}}{}{∝}1/{{ω}}²$ behavior for different secular frequencies ${ω}$. We also determine a spectral noise density ${S}E(1 MHz)=3.6(9)×{}{10}^{{-}11}$ ${V}²$ ${m}^{{-}2}$ Hz${}^{{-}1}$ at an ion electrode spacing of 310(10) ${μ}$m. We describe the experimental setup for trapping and cooling Yb${}⁺$ ions and provide frequency measurements of the ${}²{S}1/2{{↔}}²P1/2 and ²D3/2↔³D[3/2]{}1/2$ transitions for the stable $¹⁷⁰Yb⁺, ¹⁷¹Yb{}⁺$, $¹⁷²Yb⁺, ¹⁷⁴Yb{}⁺$, and $¹⁷⁶Yb⁺ isotopes which are more precise than previously published work.
