Reconstructing the formalism of quantum mechanics in the ``contextual objectivity" point of view
Philippe Grangier
In a previous preprint (quant-ph/0012122) we introduced a ``contextual objectivity" formulation of quantum mechanics (QM). A central feature of this approach is to define the quant…
Room temperature stable single-photon source
Alexios Beveratos, Sergei Kuehn, Rosa Brouri +3
We report on the realization of a stable solid state room temperature source for single photons. It is based on the fluorescence of a single nitrogen-vacancy (NV) color center in a…
Continuous variable quantum cryptography using coherent states
Frédéric Grosshans, Philippe Grangier
We propose several methods for quantum key distribution (QKD) based upon the generation and transmission of random distributions of coherent or squeezed states, and we show that th…
Nonclassical radiation from diamond nanocrystals
Alexios Beveratos, Rosa Brouri, Thierry Gacoin +2
The quantum properties of the fluorescence light emitted by diamond nanocrystals containing a single nitrogen-vacancy (NV) colored center is investigated. We have observed photon a…
Understanding the production of dual BEC with sympathetic cooling
G. Delannoy, S. G. Murdoch, V. Boyer +3
We show, both experimentally and theoretically, that sympathetic cooling of Rb atoms in the state by evaporatively cooled atoms in the state can…
