Einstein-Podolsky-Rosen Correlations of Ultracold Atomic Gases
Nir Bar-Gill, Christian Gross, Gershon Kurizki +2
Einstein, Podolsky & Rosen (EPR) pointed out that correlations induced between quantum objects will persist after these objects have ceased to interact. Consequently, their joint c…
Quantum Interference between a Single-Photon Fock State and a Coherent State
Armin Windhager, Martin Suda, Christoph Pacher +2
We derive analytical expressions for the single mode quantum field state at the individual output ports of a beam splitter when a single-photon Fock state and a coherent state are…
Cavity QED with an ultracold ensemble on a chip: prospects for strong magnetic coupling at finite temperatures
Kathrin Henschel, Johannes Majer, Jörg Schmiedmayer +1
We study the nonlinear dynamics of an ensemble of cold trapped atoms with a hyperfine transition magnetically coupled to a resonant microwave cavity mode. Despite the minute single…
Kochen-Specker theorem studied with neutron interferometer
Yuji Hasegawa, Katharina Durstberger-Rennhofer, Stephan Sponar +1
The Kochen-Specker theorem theoretically shows evidence of the incompatibility of noncontextual hidden variable theories with quantum mechanics. Quantum contextuality is a more gen…
Experimental Evidence of Quantum Randomness Incomputability
Cristian S. Calude, Michael J. Dinneen, Monica Dumitrescu +1
In contrast with software-generated randomness (called pseudo-randomness), quantum randomness is provable incomputable, i.e.\ it is not exactly reproducible by any algorithm. We pr…
