(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...
For the last decade, scientists have been making giant leaps in their ability to build and control systems based on the bizarre rules of quantum mechanics, which describe the behavior of particles at the subatomic scale.

Over the past few years, many physicists worldwide have conducted research investigating chaos in quantum systems composed of strongly interacting particles, also known as many-body chaos. The study of many-body chaos has ...
(Phys.org)—As developed by Claude Shannon, information theory defines channel capacity as the maximum rate at which information can be sent through the channel. This capacity can be mathematically described using a graph ...
