Randomness and the Beast (in Quantum Computing)

Cologne, 8th of July 2020

Engineers hate them. These guys show you the one neat trick to fix your quantum computer in the throw of a dice!

Sometimes I’m really picky about music, I want to listen to that one song stuck in my head. But more often, I’m much more relaxed about it, I go to Spotify, click a playlist for my mood, and let it randomly choose the songs for me. I’m not interested in listening to one specific song, I care more about the overall mood. Maybe something cheerful and upbeat because I’m exercising? Or maybe some lo-fi beats because I want to chill or study.

Is quantum advantage moving too fast for you to keep up?

– An overview of the recent developments in quantum computing –

Vienna, 12th of October, 2019:
Eliud Kipchoge became the first human to run a sub 2-hour marathon. Once believed to be unattainable, his time, 1:59:40, will not be officially recognized as a world record [1]. The reason for this is that the experiment to run 26.2 miles in under two hours was conducted under specific conditions which are not comparable to standard racing situations. Having an electric car and a team of 41 world-class runners in front of him, setting the pace, he broke “the last barrier of modern athletics”. Or to put it in his own words: “Vienna is about running and breaking history, like the first man on the moon.”  Continue reading “Is quantum advantage moving too fast for you to keep up?”

Quantum Simulation Cookbook

Pictorial Quantum Simulation: Atoms are sitting in a lattice built up by standing light waves, ready to be used for studying the most intriguing questions of state of the art research.


Supercomputers are cornerstones of modern industry. They help to design complicated objects like aircraft, provide the handling of big data sets in AI, trade shares at stock exchanges and set the standards for today’s encryption. However, there exist highly complex problems involving the smallest building blocks of our world which cannot be solved on these supercomputers yet. Continue reading “Quantum Simulation Cookbook”

Scotty – Quantum beam me up!

How information can be teleported through the two most counter-intuitive properties of quantum mechanics.

We all know the quantum world is weird, but in no place does it become as weird as in the protocol allowing almost instant transportation of information from one place to the other termed “quantum teleportation”. That may sound like its impossible – but what if I tell you that this can even be done without the recipient of the information knowing? And that this technology is about to make communication absolutely eavesdrop-safe?
