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 ...

How can one create a random stream of bits suitable for use in encryption and embed this solution in an FPGA? Random numbers in cryptography are key (pun intended). They can be a weak point in a ...

Privacy is one of society’s most valued qualities. The ability to send private messages and to carry out financial transactions without fear of being monitored lies ...

While world events are often difficult to predict, true randomness is surprisingly hard to find. In recent years, physicists have turned to quantum mechanics for a solution, using the inherently ...

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 ...
