(Phys.org)—In quantum entanglement, two particles are correlated in such a way that any action on one of them affects the other even when they are far apart. The traditional methods of measuring the degree of quantum entanglement ...
Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ...

(PhysOrg.com) -- Few people doubt the "quantumness" of entanglement. Quantifying the quantum correlation of entanglement is something that is relatively regular right now. However, things change a bit when it comes to quantum ...
Austrian physicist Erwin Schrödinger (1887-1961), one of the giants of contemporary science, considered entanglement the most interesting property in quantum mechanics. In his view, it was this phenomenon that truly distinguished ...
