Peeking into the quantum random number generator developed at DTU physics reveals a lot of seemingly ordinary optics and electronics. But together, the components form s high-speed and ultra-secure source of true randomness, enabled by quantum physics.

High-speed quantum random number generator secure against quantum attacks

At first glance, random numbers may seem trivial to produce and utterly useless. Not an easy sell. Isn’t it just a matter of flipping a coin? Not quite!
