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…
Bubble Clustering Decoder for Quantum Topological Codes
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
Quantum computers are highly vulnerable to noise, necessitating the use of error-correcting codes to protect stored data. Errors must be continuously corrected over time to counter…
Cylindrical and Möbius Quantum Codes for Asymmetric Pauli Errors
Lorenzo Valentini, Diego Forlivesi, Marco Chiani
In the implementation of quantum information systems, one type of Pauli error, such as phase-flip errors, may occur more frequently than others, like bit-flip errors. For this reas…
