New research demonstrates that particles at the quantum level can in fact be seen as behaving something like billiard balls rolling along a table, and not merely as the probabilistic smears that the standard interpretation ...

Here's a love story at the smallest scales imaginable: particles of light. It is possible to have particles that are so intimately linked that a change to one affects the other, even when they are separated at a distance.

(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 ...
(Phys.org)—A team of researchers at Harvard University has developed a way to measure entanglement entropy in many-body systems. In their paper published in the journal Nature, the team describes the technique they used ...
Researchers from Stanford have advanced a long-standing problem in quantum physics – how to send "entangled" particles over long distances.
