Quantum Maxwell Erasure Decoder for qLDPC codes
Bruno Costa Alves Freire, François-Marie Le Régent, Anthony Leverrier
We introduce a quantum Maxwell erasure decoder for CSS quantum low-density parity-check (qLDPC) codes that extends peeling with bounded guessing. Guesses are tracked symbolically a…

Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
