The discovery of superconductivity more than a century ago has significantly changed our world.
A group of physicists at the University of Basel, in Switzerland, has found via experimentation that the Einstein-Podolsky-Rosen paradox still holds even when scaled up. Paolo Colciaghi, Yifan Li, Philipp Treutlein and Tilman ...
Scientists from the Max Planck Institute for the Science of Light and the Friedrich-Alexander-Universität Erlangen-Nürnberg, in cooperation with Sandia National Laboratories, have successfully created photon pairs at several ...
