If you want to pick a winner in a drawing, take samples for statistical purposes, or any of hundreds of other technical tasks you are going to need a source of random numbers. If you have ever looked ...

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 ...

Say the words “quantum supremacy” at a gathering of computer scientists, and eyes will likely roll. The phrase refers to the idea that quantum computers will soon cross a threshold where they’ll ...

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 ...

Sometimes you need random numbers — and properly random ones, at that. Hackaday Alum [Sean Boyce] whipped up a rig that serves up just that, tasty random bytes delivered fresh over MQTT. [Sean] tells ...

When a computer generates a “random” number, it goes through certain algorithms that will allow it to come up with that number, which means it wasn’t really random after all. Random numbers are ...

Although schemes to generate random-looking numbers are easy to come up with, assessing their security — the extent to which they are truly unpredictable to a potential adversary — is notoriously ...

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 ...

Researchers have developed a method for generating numbers guaranteed to be random, through the use of quantum mechanics. The experimental technique surpasses all previous methods for ensuring the ...
