Quantum physics concerns a world of infinitely small things. But for years, researchers from the University of Geneva (UNIGE), Switzerland, have been attempting to observe the properties of quantum physics on a larger scale, even macroscopic. In January 2011, they managed to entangle crystals, therefore surpassing the atomic dimension. Now, Professor Nicolas Gisin's team has successfully entangled two optic fibers, populated by 500 photons. Unlike previous experiments which were carried out with the fiber optics of one photon, this new feat (which has been published in Nature Physics) begins to answer a fundamental question: can quantum properties survive on a macroscopic level?
