Abstract: [...] Relay-BP is inherently parallel, enabling rapid low-footprint decoding with FPGA or ASIC real-time implementations, similar to standard BP. A core aspect of our decoder is its enhancement of the standard BP algorithm by incorporating disordered memory strengths. This dampens oscillations and breaks symmetries that trap traditional BP algorithms.

WTF does it even mean to run a quantum error correction algorithm on a (classical) FPGA?
It means the next tech hype cycle is about to begin
