Adiabatic cooling of a single trapped ion
Gregers Poulsen, Michael Drewsen
We present experimental results on adiabatic cooling of a single 40Ca+ ion in a linear radiofrequency trap. After a period of laser cooling, the secular frequency along the rf-fiel…

Ground state sideband cooling of an ion in a room temperature trap with a sub-Hertz heating rate
G. Poulsen, Y. Miroshnychenko, M. Drewsen
We demonstrate resolved sideband laser cooling of a single 40Ca+ ion in a macroscopic linear radio frequency trap with a radial diagonal electrode spacing of 7 mm and an rf drive f…

Coherent Manipulation of a Ca Spin Qubit in a Micro Ion Trap
U. G. Poschinger, G. Huber, F. Ziesel +8
We demonstrate the implementation of a spin qubit with a single Ca ion in a micro ion trap. The qubit is encoded in the Zeeman ground state levels mJ=+1/2 and mJ=-1/2 of the S1/2 s…
