The quest for truly random numbers is something to which scientists and engineers have devoted a lot of time and effort. The trick is to find an unpredictable source of naturally occurring noise that ...

How can you generate random bits? Some people think it’s not easy, others will tell you that it’s pretty damn hard, and then there are those who wonder if it is possible at all. Of course, it is easy ...

Generating random numbers is harder than you might think, and the security of digital communications depends on it. Now a new method that uses lasers to produce streams of truly random numbers faster ...

Computers struggle to create randomness, but a new approach may finally enable them to generate a truly random number. Such numbers are a vital ingredient for cryptographic algorithms and scientific ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

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 ...
