Quantum Mechanics in Game Theory

Researchers at the Universities of Bristol and Geneva have discovered a link between quantum mechanics and game theory. According to a paper published by Nicolas Brunner and Noah Linden in Nature Communication, players’ use of entangled quantum particles in Bayesian games “will lead to novel joint strategies, impossible to achieve classically.”

According to classical physics, location limits the performance of players. Brunner and Linder, however, show that the non-local features of quantum mechanics—that is, the ability of entangled particles to communicate when separated—are also reflected in games. According to Dr. Brunner:

Such an advantage could, for instance, be useful in auctions which are well described by the type of games that we considered.  Therefore, our work not only opens a bridge between two remote scientific communities, but also opens novel possible applications for quantum technologies.
