Quantum computing with trapped ions
H. Haeffner, C. F. Roos, R. Blatt
Quantum computers hold the promise to solve certain computational task much more efficiently than classical computers. We review the recent experimental advancements towards a quan…
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…
Ion trap quantum gates with amplitude-modulated laser beams
Christian F. Roos
In ion traps, entangling gate operations can be realized by a bichromatic pair of laser beams that collectively interact with the ions. In this paper, a new method of modelling the…
'Designer atoms' for quantum metrology
C. F. Roos, M. Chwalla, K. Kim +2
Entanglement is recognized as a key resource for quantum computation and quantum cryptography. For quantum metrology, the use of entangled states has been discussed and demonstrate…
Precision frequency measurements with entangled states
C. F. Roos
We demonstrate how quantum entanglement can be used for precision frequency measurements with trapped ions. In particular, we show how to suppress linear Zeeman shifts in optical f…
