Photonic microwave signals with zeptosecond level absolute timing noise
Xiaopeng Xie, Romain Bouchand, Daniele Nicolodi +11
Photonic synthesis of radiofrequency revived the quest for unrivalled microwave purity by its seducing ability to convey the benefits of the optics to the microwave world. In this…
Three Dimensional Raman Cooling using Velocity Selective Rapid Adiabatic Passage
Axel Kuhn, Hélène Perrin, Wolfgang Hänsel +1
We present a new and efficient implementation of Raman cooling of trapped atoms. It uses Raman pulses with an appropriate frequency chirp to realize a velocity selective excitation…
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,…
