Trapped-ion antennae for the transmission of quantum information
Maximilian Harlander, Regina Lechner, Michael Brownnutt +2
More than one hundred years ago Heinrich Hertz succeeded in transmitting signals over a few meters to a receiving antenna using an electromagnetic oscillator and thus proving the e…
14-qubit entanglement: creation and coherence
Thomas Monz, Philipp Schindler, Julio T. Barreiro +7
We report the creation of Greenberger-Horne-Zeilinger states with up to 14 qubits. By investigating the coherence of up to 8 ions over time, we observe a decay proportional to the…
Trapped-ion probing of light-induced charging effects on dielectrics
Maximilian Harlander, Michael Brownnutt, Wolfgang Hänsel +1
We use a string of confined Ca ions to measure perturbations to a trapping potential which are caused by light-induced charging of an anti-reflection coated window and o…
Realization of Universal Ion Trap Quantum Computation with Decoherence Free Qubits
T. Monz, K. Kim, A. S. Villar +8
Any residual coupling of a quantum computer to the environment results in computational errors. Encoding quantum information in a so-called decoherence-free subspace provides means…
Quantum teleportation with atoms: quantum process tomography
M. Riebe, M. Chwalla, J. Benhelm +4
The performance of a quantum teleportation algorithm implemented on an ion trap quantum computer is investigated. First the algorithm is analyzed in terms of the teleportation fide…
Robust state preparation of a single trapped ion by adiabatic passage
Chr. Wunderlich, Th. Hannemann, T. Koerber +5
We report adiabatic passage experiments with a single trapped Ca ion. By applying a frequency chirped laser pulse with a Gaussian amplitude envelope we reach a transfer…
How to realize a universal quantum gate with trapped ions
F. Schmidt-Kaler, H. Häffner, M. Riebe +7
We report the realization of an elementary quantum processor based on a linear crystal of trapped ions. Each ion serves as a quantum bit (qubit) to store the quantum information in…
Trapped-Atom-Interferometer in a Magnetic Microtrap
W. Hänsel, J. Reichel, P. Hommelhoff +1
We propose a configuration of a magnetic microtrap which can be used as an interferometer for three-dimensionally trapped atoms. The interferometer is realized via a dynamic splitt…
Applications of Integrated Magnetic Microtraps
J. Reichel, W. Hänsel, P. Hommelhoff +1
Lithographically fabricated circuit patterns can provide magnetic guides and microtraps for cold neutral atoms. By combining several such structures on the same ceramic substrate,…
