I am interested in all kinds of new technology with a focus on physics, electrical engineering, and computer science. I have recently finished my PhD in Quantum Information Theory within the Doctoral Programme Atoms, Light, and Molecules at the University of Innsbruck. Currently, I am working as Postdoc at the University of Innsbruck.
For millennia, people have strived to build machines that assist them in information processing tasks. Let it be simple calculating tools such as the Abacus, or complex technologies such as modern computers. Obviously, any such machine must be bound to the laws of physics. On very small scales, physics are governed by the laws of quantum mechanics. Strikingly, these may be exploited in order to gain an advantage in information processing tasks. Identifying these advantages is the main objective within Quantum Information Theory, and my studies.

My take on briefly explaining Quantum Information Theory
This short article (which is in parts an excerpt from my Disseration) is my personal attempt at briefly explaining the research field of Quantum Information Theory to a technologically interested nonexpert in quantum physics.
Falling Blocks
As a small hobby project, I have created a modest computer game utilizing 3D graphics, reminiscent of Tetris. This diverting 2player game for Windows may be downloaded here.
