Achieving Thresholds via Standalone Belief Propagation on Surface Codes
Pedro Hack, Luca Menti, Francisco Lazaro +1
The standard approach to Belief Propagation (BP) decoding passes messages on the Tanner graph of the quantum error-correcting (QEC) code, and is known to lack a threshold for the s…

Belief propagation for general graphical models with loops
Pedro Hack, Jonas Hitter, Christian B. Mendl +1
There is an increasing interest in scaling tensor network methods through belief propagation (BP), as well as increasing the accuracy of BP through tensor network methods. We devel…

Universality and classification of elementary thermal operations
Pedro Hack, Christian B. Mendl
Elementary thermal operations are thermal operations that act non-trivially on at most two energy levels of a system at the same time. They were recently introduced in order to bri…
