Randomness in Quantum Information

Welcome to the website of Markus Heinrich. I am a senior researcher at the University of Cologne, interested in wide range of topics in quantum information and quantum computing, a major part of which are related to randomness.

Current quantum devices are limited by noise, which severely affects their ability to run long quantum circuits. This is even true for early-fault tolerant devices that may be available in a couple of years. Thus, if quantum computers are supposed to solve meaningful problems in the near future, we need to understand the power and capabilities of short quantum circuits. What kind of problems can be solved using short quantum circuits and which can't? Which currently known applications can be made more efficient such that they can be solved using short quantum circuits? What tools are needed to make progress in these questions?

I am also co-organizing the Workshop on Random Quantum Circuits, the first edition of which took place in November 2024 in Amsterdam, and will be continued on a bi-yearly basis.
