Coherent Control of Trapped Ion Qubits with Localized Electric Fields
R. Srinivas, C. M. Löschnauer, M. Malinowski +8
We present a new method for coherent control of trapped ion qubits in separate interaction regions of a multi-zone trap by simultaneously applying an electric field and a spin-depe…
Coupling two laser-cooled ions via a room-temperature conductor
Da An, Alberto M. Alonso, Clemens Matthiesen +1
We demonstrate coupling between the motions of two independently trapped ions with a separation distance of 620 m. The ion-ion interaction is enhanced via a room-temperature ele…
Changes in electric-field noise due to thermal transformation of a surface ion trap
Maya Berlin-Udi, Clemens Matthiesen, P. N. Thomas Lloyd +9
We aim to illuminate how the microscopic properties of a metal surface map to its electric-field noise characteristics. In our system, prolonged heat treatments of a metal film can…
Trapping electrons in a room-temperature microwave Paul trap
Clemens Matthiesen, Qian Yu, Jinen Guo +2
We demonstrate trapping of electrons in a millimeter-sized quadrupole Paul trap driven at 1.6~GHz in a room-temperature ultra-high vacuum setup. Cold electrons are introduced into…
Distance scaling and polarization of electric-field noise in a surface ion trap
Da An, Clemens Matthiesen, Erik Urban +1
We probe electric-field noise in a surface ion trap for ion-surface distances between 50 and 300 in the normal and planar directions. We find the noise distance d…
Electric-field noise from thermally-activated fluctuators in a surface ion trap
Crystal Noel, Maya Berlin-Udi, Clemens Matthiesen +4
We probe electric-field noise near the metal surface of an ion trap chip in a previously unexplored high-temperature regime. We observe a non-trivial temperature dependence with th…
