No-cloning theorem and teleportation criteria for quantum continuous variables
Frédéric Grosshans, Philippe Grangier
We discuss the criteria presently used for evaluating the efficiency of quantum teleportation schemes for continuous variables. Using an argument based upon the difference between…
Contextual objectivity : a realistic interpretation of quantum mechanics
Philippe Grangier
An attempt is made to formulate quantum mechanics (QM) in physical rather than in mathematical terms. It is argued that the appropriate conceptual framework for QM is "contextual o…
Evaluating quantum teleportation of coherent states
Philippe Grangier, Frédéric Grosshans
We discuss the criteria for teleporting coherent states from simple considerations about information exchange during the teleportation process.
Bunching and antibunching from single NV color centers in diamond
A. Beveratos, R. Brouri, J. -P. Poizat +1
We investigate correlations between fluorescence photons emitted by single N-V centers in diamond with respect to the optical excitation power. The autocorrelation function shows c…
Quantum teleportation criteria for continuous variables
Philippe Grangier, Frederic Grosshans
We discuss the criteria presently used for evaluating the efficiency of quantum teleportation schemes for continuous variables. It is argued that the fidelity criterion used so far…
Single photon generation by pulsed excitation of a single dipole
Rosa Brouri, Alexios Beveratos, Jean-Philippe Poizat +1
The fluorescence of a single dipole excited by an intense light pulse can lead to the generation of another light pulse containing a single photon. The influence of the duration an…
