Redefining quantum machine learning. New study from team of quantum physicists at Freie Universität Berlin challenges traditional understanding of quantum machine learning. Press release of the FU Berlin

Where quantum computers can score. The travelling salesman problem is considered a prime example of a combinatorial optimisation problem. Now a Berlin team led by theoretical physicist Prof. Dr. Jens Eisert of Freie Universität Berlin and HZB has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods. Press release of the HZB.

Two promising fields. Machine learning and quantum computing. In the Nature Communications publication, an interdisciplinary team comprising mathematicians, computer scientists, and physicists from the University of Chicago, MIT, and FU Berlin investigated the potential of quantum computers in addressing machine learning problems. MATH+ member Jens Eisert contributed the central idea of how a quantum advantage could be created, originating from a MATH+ project. Press release of MATH+.
