Title: Coherent network computing for the solution of
optimization problems


Finding the energetic ground state of a magnet with disordered internal couplings is a complicated combinatorial problem. This so-called spin-glass problem has no analytic solution and even numerical techniques are found to be inefficient. It is known that many important optimization problems in machine learning, logistics, computer chip design, and DNA sequencing can be mathematically mapped to an equivalent spin-glass problem. A method for solving this problem can thus serve as a blueprint for approaching a large class of mathematical optimizations. This motivates research on analog spin-glass simulators as a new class of computational devices (coherent network computing). I will give an overview of the experimental progress in this area including the achievements of our group.


Jan Klaers did his PhD at the University of Bonn in 2011. After a postdoc stay at ETH Zurich, he started to build up a research group at the University of Twente in 2017. His group investigates networks of coupled photon Bose-Einstein condensates and their potential application in solving optimization problems.
