Cryogenic platform for coupling color centers in diamond membranes to a fiberbased microcavity
M. Salz, Y. Herrmann, A. Nadarajah +6
We operate a fiberbased cavity with an inserted diamond membrane containing ensembles of silicon vacancy centers (SiV) at cryogenic temperatures K. The setup, sample f…
A Quantum Repeater Node with Trapped Ions: A Realistic Case Example
Andreas Daniel Pfister, Marcel Salz, Max Hettrich +2
We evaluate the feasibility of the implementation of two quantum repeater protocols with an existing experimental platform based on a Ca-ion in a segmented micro trap, a…
Measurement of dipole matrix elements with a single trapped ion
M. Hettrich, T. Ruster, H. Kaufmann +4
We demonstrate a new method for the direct measurement of atomic dipole transition matrix elements based on techniques developed for quantum information purposes. The scheme consis…
Experimental realization of fast ion separation in segmented Paul traps
Thomas Ruster, Claudia Warschburger, Henning Kaufmann +7
We experimentally demonstrate fast separation of a two-ion crystal in a microstructured segmented Paul trap. By the use of spectroscopic calibration routines for the electrostatic…
Controlling fast transport of cold trapped ions
Andreas Walther, Frank Ziesel, Thomas Ruster +6
We realize fast transport of ions in a segmented micro-structured Paul trap. The ion is shuttled over a distance of more than 10^4 times its groundstate wavefunction size during on…
Interaction of a Laser with a Qubit in Thermal Motion and its Application to Robust and Efficient Readout
U. Poschinger, A. Walther, M. Hettrich +2
We present a detailed theoretical and experimental study on the optical control of a trapped-ion qubit subject to thermally induced fluctuations of the Rabi frequency. The coupling…
A single ion as a shot noise limited magnetic field gradient probe
Andreas Walther, Ulrich Poschinger, Frank Ziesel +4
It is expected that ion trap quantum computing can be made scalable through protocols that make use of transport of ion qubits between sub-regions within the ion trap. In this scen…
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…
