Light, matter, and quantum randomness generation: A relativistic quantum information perspective. (arXiv:1710.06875v1 [quant-ph])  hep-th updates on arXiv.org on 2017-10-21 12:07pm GMT Authors: Richard Lopp, Eduardo Martin-Martinez We study how quantum randomness generation based on unbiased measurements on a hydrogen-like atom can get compromised by virtue of the unavoidable coupling of the atom with the electromagnetic field. Concretely, we show that an adversary... Read more →

Experimental certification of millions of genuinely entangled atoms in a solid  Nature Communications - current - nature.com science feeds on 2017-10-13 5:00am GMT Experimental certification of millions of genuinely entangled atoms in a solid Nature Communications, Published online: 13 October 2017; doi:10.1038/s41467-017-00898-6 The presence of entanglement in macroscopic systems is notoriously difficult to observe. Here, the authors develop a witness which... Read more →
