New application of a quantum diamond detector for sensing in biology

An international consortium headed by researchers from the section for Quantum Physics and Information Technology, QPIT, and the DNRF center for macroscopic quantum states...

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!
