High-fidelity quantum state control of a polar molecular ion in a cryogenic environment
Dalton Chaffee, Baruch Margulis, April Sheffield +5
We use a quantum-logic spectroscopy (QLS) protocol to control the quantum state of a CaH+ ion in a cryogenic environment, in which reduced thermal radiation extends rotational stat…
Quantum state tracking and control of a single molecular ion in a thermal environment
Yu Liu, Julian Schmidt, Zhimin Liu +3
Understanding molecular state evolution is central to many disciplines, including molecular dynamics, precision measurement, and molecule-based quantum technology. Details of the e…
Coupling a single atomic quantum bit to a high finesse optical cavity
A. B. Mundt, A. Kreuter, C. Becher +4
The quadrupole S -- D optical transition of a single trapped Ca ion, well suited for encoding a quantum bit of information, is coherently coupled to the standin…
Experiments towards quantum information with trapped Calcium ions
D. Leibfried, C. Roos, P. Barton +8
Ground state cooling and coherent manipulation of ions in an rf-(Paul) trap is the prerequisite for quantum information experiments with trapped ions. With resolved sideband coolin…
Ground state cooling, quantum state engineering and study of decoherence of ions in Paul traps
F. Schmidt-Kaler, Ch. Roos, H. C. Naegerl +12
We investigate single ions of in Paul traps for quantum information processing. Superpositions of the S electronic ground state and the metastable D sta…
Quantum state engineering on an optical transition and decoherence in a Paul trap
Ch. Roos, Th. Zeiger, H. Rohde +5
A single Ca+ ion in a Paul trap has been cooled to the ground state of vibration with up to 99.9% probability. Starting from this Fock state |n=0> we have demonstrated coherent qua…
