Journal Club for Quantum Physics and Machine Learning



Next Journal Club Meeting: Tuesday, 23rd February 2021, 4:30pm CET.

Evert van Nieuwenburg (University of Copenhagen) will present the following paper: A NEAT Quantum Error Decoder.

Abstract: We investigate the use of the evolutionary NEAT algorithm for finding a quantum error decoder for the toric code. The problem is formulated as a single player game, making it amenable to a reinforcement learning approach, with an agent whose policy network we directly optimise. We find that these NEAT-optimized network decoders have similar performance to previously reported machine-learning based decoders, but use roughly three to four orders of magnitude fewer parameters to do so.
