Journal ArticleDOI
Experimental Realization of Einstein-Podolsky-Rosen-Bohm Gedankenexperiment : A New Violation of Bell's Inequalities
TL;DR: In this article, the linear-polarization correlation of pairs of photons emitted in a radiative cascade of calcium has been measured using two-channel polarizers (i.e., optical analogs of Stern-Gerlach filters).
Journal ArticleDOI
Experimental Tests of Realistic Local Theories via Bell's Theorem
TL;DR: In this article, the linear polarization correlation of the photons emitted in a radiative atomic cascade of calcium was measured, in excellent agreement with the quantum mechanical predictions, strongly violate the generalized Bell's inequalities, and rule out the whole class of realistic local theories.
Journal ArticleDOI
Quantum key distribution using gaussian-modulated coherent states
Frédéric Grosshans,Gilles Van Assche,Jérôme Wenger,Rosa Brouri,Nicolas J. Cerf,Philippe Grangier +5 more
TL;DR: This work proposes and experimentally demonstrate a quantum key distribution protocol based on the transmission of gaussian-modulated coherent states and shot-noise-limited homodyne detection, which is in principle secure for any value of the line transmission, against gaussian individual attacks based on entanglement and quantum memories.
Journal ArticleDOI
Continuous Variable Quantum Cryptography Using Coherent States
TL;DR: This work proposes several methods for quantum key distribution (QKD) based on the generation and transmission of random distributions of coherent or squeezed states, and shows that they are secure against individual eavesdropping attacks.
Journal ArticleDOI
Experimental Evidence for a Photon Anticorrelation Effect on a Beam Splitter: A New Light on Single-Photon Interferences
TL;DR: In this article, the authors report on two experiments using an atomic cascade as a light source, and a triggered detection scheme for the second photon of the cascade, which is in contradiction with any classical wave model of light but in agreement with a quantum description involving single-photon states.
