High fidelity entanglement of 43Ca+ hyperfine clock states
G. Kirchmair, J. Benhelm, F. Zähringer +3
In an experiment using the odd calcium isotope 43Ca+ we combine the merits of a high fidelity entangling operation on an optical transition (optical qubit) with the long coherence…
Deterministic entanglement of ions in thermal states of motion
G. Kirchmair, J. Benhelm, F. Zähringer +3
We give a detailed description of the implementation of a Molmer-Sorensen gate entangling two Ca+ ions using a bichromatic laser beam near-resonant with a quadrupole transition. By…
Experimental quantum information processing with 43Ca+ ions
J. Benhelm, G. Kirchmair, C. F. Roos +1
For quantum information processing (QIP) with trapped ions, the isotope 43Ca+ offers the combined advantages of a quantum memory with long coherence time, a high fidelity read out…
Towards fault-tolerant quantum computing with trapped ions
J. Benhelm, G. Kirchmair, C. F. Roos +1
Today ion traps are among the most promising physical systems for constructing a quantum device harnessing the computing power inherent in the laws of quantum physics. The standard…
High-fidelity ion-trap quantum computing with hyperfine clock states
L. Aolita, K. Kim, J. Benhelm +2
We propose the implementation of a geometric-phase gate on magnetic-field-insensitive qubits with -dependent forces for trapped ion quantum computing. The force is exerted…
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…
