A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level from one to 54 centimeters. In their paper published in the journal Nature, the team describes ...
Despite huge advances in science over the past century, our understanding of nature is still far from complete. Not only have scientists failed to find the Holy Grail of physics—unifying the very large (general relativity) ...

(Phys.org) —While entangling cats with atoms is not exactly an active area of research in any physics lab today (as far as anyone knows), many physicists are working on a close analogy of Schrödinger's cat experiment. ...
(PhysOrg.com) -- Although the uncertainty principle is probably the most well-known example of a fundamental limitation of measurement precision in quantum mechanics, it is not the only one. In fact, every physical system ...
(PhysOrg.com) -- When waves -- regardless of whether light or sound -- collide, they overlap creating interferences. Austrian and Canadian quantum physicists have now been able to rule out the existence of higher-order interferences ...
