Practical Low-Weight Codes for Energy-Efficient Bus Encoding
Lorenzo Valentini, Marco Chiani
We consider the transmission of data encoded into binary messages, with the goal of minimizing the Hamming distance, i.e., the number of bit-flips, between consecutive messages. Th…
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.…
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…
Ensemble Average Analysis of Non-Adaptive Group Testing with Sparse Pooling Graphs
Emna Ben Yacoub, Gianluigi Liva, Enrico Paolini +1
A combinatorial analysis of the false alarm (FA) and misdetection (MD) probabilities of non-adaptive group testing with sparse pooling graphs is developed. The analysis targets the…
