Fast quantum random number generator could advance cryptography on the cheap

Recommended Posts

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 unpredictable behavior of photons to generate the truly random numbers that underpin many modern cryptographic protocols. Now, a new study promises to make this process of quantum random number generation more accessible, by showing that it is possible to produce certifiably random numbers quickly using a system built with off-the-shelf components.


Remark: True RNG's could be very interesting as entropy sources for ITC experiments with voices and images.
