(Phys.org)—Physicists have reported some of the strongest evidence yet that that the quantum world does not obey local realism by demonstrating new evidence for the existence of quantum entanglement. By performing an essentially ...
(Phys.org)—Stars, quasars, and other celestial objects generate photons in a random way, and now scientists have taken advantage of this randomness to generate random numbers at rates of more than one million numbers per ...
(Phys.org)—Theoretically, the laws of quantum mechanics – particularly the "no-cloning theorem" – guarantee that any attempt at counterfeiting a credit card, bill, coin, token, etc., will fail if the object is embedded ...
(PhysOrg.com) -- In quantum cryptography, scientists use quantum mechanical effects to encrypt and then communicate confidential information. Although quantum cryptography codes are unbreakable in principle, even the best ...
(PhysOrg.com) -- The latest test in quantum mechanics provides even stronger support than before for the view that nature violates local realism and is thus in contradiction with a classical worldview. By performing an experiment ...
Adding to strong recent demonstrations that particles of light perform what Einstein called "spooky action at a distance," in which two separated objects can have a connection that exceeds everyday experience, physicists ...

(Phys.org)—A team of researchers working at Delft University in The Netherlands, has perhaps succeeded in closing the two loopholes that have prevented proving that local realism does not hold at the quantum level. They ...
(Phys.org) —BugBuster: one bot can test almost every function on a website. This tiny revolution for web developers means great gains in time and reliability. To overcome problems that come with using websites, which can ...
