Feedback receiver for quantum state discrimination

Over the course of two years, we demonstrated a number of improvements to the problem of efficiently telling overlapping quantum states apart. Here, we review these results...

Quantum theory and atomic physics Optics
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!
