A quantum detector for photon entanglement
J. Huwer, J. Ghosh, N. Piro +3
We use a single trapped 40Ca+ ion as a resonant, polarization-sensitive absorber to detect and characterize the entanglement of tunable narrowband photon pairs from a spontaneous p…
Quantum to Classical Transition in a Single-Ion Laser
François Dubin, Carlos Russo, Helena G. Barros +4
Stimulated emission of photons from a large number of atoms into the mode of a strong light field is the principle mechanism for lasing in "classical" lasers. The onset of lasing i…
Polarization-correlated photon pairs from a single ion
F. Rohde, J. Huwer, N. Piro +4
In the fluorescence light of a single atom, the probability for emission of a photon with certain polarization depends on the polarization of the photon emitted immediately before…
Resonant interaction of a single atom with single photons from a down-conversion source
C. Schuck, F. Rohde, N. Piro +7
We observe the interaction of a single trapped calcium ion with single photons produced by a narrow-band, resonant down-conversion source [A. Haase et al., Opt. Lett. 34, 55 (2009)…
Bandwidth-tunable single photon source in an ion trap quantum network
M. Almendros, J. Huwer, N. Piro +5
We report a tunable single-photon source based on a single trapped ion. Employing spontaneous Raman scattering and in-vacuum optics with large numerical aperture, single photons ar…
Raman spectroscopy of a single ion coupled to a high-finesse cavity
C. Russo, H. G. Barros, A. Stute +9
We describe an ion-based cavity-QED system in which the internal dynamics of an atom is coupled to the modes of an optical cavity by vacuum-stimulated Raman transitions. We observe…
Quantum interference from remotely trapped ions
S. Gerber, D. Rotter, M. Hennrich +7
We observe quantum interference of photons emitted by two continuously laser-excited single ions, independently trapped in distinct vacuum vessels. High contrast two-photon interfe…
