Frequency Feedback for Two-Photon Interference from Separate Quantum Dots
Michael Zopf, Tobias Macha, Robert Keil +7
We employ active feedback to stabilize the frequency of single photons emitted by two separate quantum dots to an atomic standard. The transmission of a single, rubidium-based Fara…
Cavity-Modified Collective Rayleigh Scattering of Two Atoms
René Reimann, Wolfgang Alt, Tobias Kampschulte +5
We report on the observation of cooperative radiation of exactly two neutral atoms strongly coupled to the single mode field of an optical cavity, which is close to the lossless-ca…
Quantum erasure with causally disconnected choice
Xiao-song Ma, Johannes Kofler, Angie Qarry +9
The counterintuitive features of quantum physics challenge many common-sense assumptions. In an interferometric quantum eraser experiment, one can actively choose whether or not to…
Feasibility of 300 km Quantum Key Distribution with Entangled States
Thomas Scheidl, Rupert Ursin, Alessandro Fedrizzi +8
A significant limitation of practical quantum key distribution (QKD) setups is currently their limited operational range. It has recently been emphasized (X. Ma, C.-H. F. Fung, and…
Violation of local realism with freedom of choice
Thomas Scheidl, Rupert Ursin, Johannes Kofler +8
Bell's theorem shows that local realistic theories place strong restrictions on observable correlations between different systems, giving rise to Bell's inequality which can be vio…
