Performance Limits of Fault-Tolerant Quantum Error Correction Schemes
Lorenzo Valentini, Diego Forlivesi, Marco Chiani
Quantum error correction (QEC) is essential for realizing scalable quantum computation. However, when evaluating its benefits, most analyses assume idealized components, overlookin…
Fault-Tolerant Cut-Cat State Syndrome Extraction for Quantum Codes
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
Reliable quantum computation requires fault-tolerant protocols to prevent errors from propagating during syndrome extraction in quantum error correction. We present a novel fault-t…
Dimensioning of Quantum Memories for Distilled Quantum EPR Packets
Lorenzo Valentini, Diego Forlivesi, Andrea Talarico +1
The quantum Internet envisions a network where information is transmitted through entanglement, with Einstein-Podolsky-Rosen (EPR) pairs serving as one of the fundamental carriers.…
Flag at origin: a modular fault-tolerant preparation for CSS codes
Diego Forlivesi, David Amaro
Fault-tolerant (FT) preparation of diverse logical stabilizer states in quantum error-correcting (QEC) codes is essential for FT computation. Existing constructions of these FT cir…
Performance Analysis of Quantum CSS Error-Correcting Codes via MacWilliams Identities
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
We analyze the performance of quantum stabilizer codes, one of the most important classes for practical implementations, on both symmetric and asymmetric quantum channels. To this…
Restart Belief: A General Quantum LDPC Decoder
Lorenzo Valentini, Diego Forlivesi, Andrea Talarico +1
Hardware-friendly quantum low-density parity-check (QLDPC) decoders are commonly built upon belief propagation (BP) processing. Yet, quantum degeneracy often prevents BP from achie…
