GPU-Accelerated Syndrome Decoding for Quantum LDPC Codes below the 63 s Latency Threshold
Oscar Ferraz, Bruno Coutinho, Gabriel Falcao +3
This paper presents a GPU-accelerated decoder for quantum low-density parity-check (QLDPC) codes that achieves sub- s latency, below the surface code decoder's real-time thr…

Fault-tolerant noise guessing decoding of quantum random codes
Diogo Cruz, Francisco A. Monteiro, André Roque +1
This work addresses the open question of implementing fault-tolerant QRLCs with feasible computational overhead. We present a new decoder for quantum random linear codes (QRLCs) ca…

Efficient entanglement purification based on noise guessing decoding
André Roque, Diogo Cruz, Francisco A. Monteiro +1
In this paper, we propose a novel bipartite entanglement purification protocol built upon hashing and upon the guessing random additive noise decoding (GRAND) approach recently dev…
