(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 ...
Whenever we need to communicate in secret, a cryptographic key is needed. For this key to work, it must consist of numbers chosen at random without any structure – just the opposite of using the birthdate of our favourite ...

(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 ...
The Tohoku University research group of Professor Keiichi Edamatsu and Postdoctoral fellow Naofumi Abe has demonstrated dynamically and statically unpolarized single-photon generation using diamond. This result is expected ...

(Phys.org)—Generating a sequence of random numbers may be more difficult than it sounds. Although the numbers may appear random, how do you know for sure that they don't actually follow some complex, underlying pattern? ...
