Self-testing is a promising method to infer the physics underlying specific quantum experiments using only collected measurements. While this method can be used to examine bipartite pure entangled states, so far it could ...
Classically, information travels in one direction only, from sender to receiver. In a new paper, however, physicists Flavio Del Santo at the University of Vienna and Borivoje Dakić at the Austrian Academy of Sciences have ...
(Phys.org)—Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement?
(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's future behavior, ...
(PhysOrg.com) -- "One of the things we have been studying is how the world works on a really small scale," Bruno Sanguinetti, a scientist at the University of Geneva in Switzerland tells PhysOrg.com. "At the quantum level, ...
(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 ...
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks as well as ...

The world we experience is governed by classical physics. How we move, where we are, and how fast we're going are all determined by the classical assumption that we can only exist in one place at any one moment in time.
