Pathfinder-BP: A Low-Latency Recursive Decoder for Topological Codes
Stefano Tinelli, Francisco Lázaro, Francisco García Herrero
We propose Pathfinder-BP, a recursive decoder for topological quantum codes that combines belief propagation with controlled bit-flipping. An initial BP pass identifies and permane…

Optimal Single-Shot Decoding of Quantum Codes
Aldo Cumitini, Stefano Tinelli, Balázs Matuz +2
We discuss single-shot decoding of quantum Calderbank-Shor-Steane codes with faulty syndrome measurements. We state the problem as a joint source-channel coding problem. By adding…

Age of Information in Slotted ALOHA With Energy Harvesting
Khac-Hoang Ngo, Giuseppe Durisi, Alexandre Graell i Amat +2
We examine the age of information (AoI) of a status update system that incorporates energy harvesting and uses the slotted ALOHA protocol. We derive analytically the average AoI an…
