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…
Absolute frequency measurement of the 40Ca+ S1/2 - D5/2 clock transition
M. Chwalla, J. Benhelm, K. Kim +12
We report on the first absolute transition frequency measurement at the 10^{-15} level with a single, laser-cooled 40Ca+ ion in a linear Paul trap. For this measurement, a frequenc…
Realization of the quantum Toffoli gate with trapped ions
T. Monz, K. Kim, W. Hänsel +6
Algorithms for quantum information processing are usually decomposed into sequences of quantum gate operations, most often realized with single- and two- qubit gates[1]. While such…
Precision spectroscopy with two correlated atoms
M. Chwalla, K. Kim, T. Monz +4
We discuss techniques that allow for long coherence times in laser spectroscopy experiments with two trapped ions. We show that for this purpose not only entangled ions prepared in…
Nonlinear coupling of continuous variables at the single quantum level
C. F. Roos, T. Monz, K. Kim +4
We experimentally investigate nonlinear couplings between vibrational modes of strings of cold ions stored in linear ion traps. The nonlinearity is caused by the ions' Coulomb inte…
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…
