Fraunhofer Institute for Photonic Microsystems IPMS announces Q‑Dice, a high‑performance Quantum Random Number Generator (QRNG) that generates randomness based on quantum vacuum fluctuations. The ...

Random number sequences are essential to a host of encryption schemes. But true randomness in the strict sense is not possible in the classical world; it only occurs in quantum-mechanical processes.

Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could strengthen cryptography and other security systems.

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can.

There will be an app for that: making random numbers on a mobile phone. (Courtesy: Marketa Michalkova) Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries ...

Randomness rules the very fabric of reality. So it only makes sense that scientists have figured out how to use nature’s randomness as a tool in our mundane world. Random numbers go hand-in-hand with ...

Random number generators aren’t just some niche toy of interest only to mathematicians. They’re also crucial to keeping our computer systems safe from hackers and those who would seek to do us harm.

What do you do, when you need a random number in your programming? The chances are that you reach for your environment’s function to do the job, usually something like rand() or similar. This returns ...
