Experimental creation and analysis of displaced number states
F. Ziesel, T. Ruster, A. Walther +4
We create displaced number states, which are nonclassical generalizations of coherent states, of a vibrational mode of a single trapped ion.
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…
Electric field compensation and sensing with a single ion in a planar trap
Sankaranarayanan Selvarajan, Nikos Daniilidis, Sönke Möller +5
We use a single ion as an movable electric field sensor with accuracies on the order of a few V/m. For this, we compensate undesired static electric fields in a planar RF trap and…
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…
A trapped-ion local field probe
Gerhard Huber, Frank Ziesel, Ulrich Poschinger +2
We introduce a measurement scheme that utilizes a single ion as a local field probe. The ion is confined in a segmented Paul trap and shuttled around to reach different probing sit…
