Quantum physics can be exploited to generate true random numbers, which have important roles in many applications, especially in cryptography. Genuine randomness from the measurement of a quantum ...

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in applications ...

Physicists have completed a study comparing the "randomness" in pi to that produced by random number generators. They have found that while sequences of digits from pi are indeed an acceptable ...

SAN FRANCISCO, RSA Conference -- In light of yet another SSL vulnerability this week, any improvements to the underpinnings of encryption would be welcome. One weakness of encryption algorithms -- one ...

Randomness is a pursuit in a similar vein to metrology or time and frequency, in that inordinate quantities of effort can be expended in pursuit of its purest form. The Holy Grail is a source of ...

There is a growing sense among physicists that all physical processes can be thought of in terms of the information they store and process; by some accounts information is the basic unit of existence ...
