| Experimentally testing nonlocality in many-body systems Posted: 20 Jun 2014 09:04 AM PDT Researchers constructed multipartite Bell inequalities built from the easiest-to-measure quantities, the two-body correlators, which are capable of revealing nonlocality in many-body systems. As these are considered a fundamental resource for quantum information theory, this study will pave a new path towards experimental detection of nonlocality in large composite quantum systems.  |
| Posted: 19 Jun 2014 06:56 AM PDT A rectangular plastic board with 384 small wells is the setting for a chemist-researcher. The chemist carefully pipets some drops of sugar solution into a row of the tiny reaction vessels. As soon as the fluid has mixed with the contents of the vessels, fluorescence starts in some of the wells. What the chemist does here – with his own hands – could also be called in a very simplified way, the 'sweetest computer in the world'. The reason: the sugar molecules used are part of a chemical sequence for information processing.  |
