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…
Quantum codes for asymmetric channels: ZZZY surface codes
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
We introduce surface ZZZY codes, a novel family of quantum error-correcting codes designed for asymmetric channels. Derived from standard surface codes through tailored modificatio…
Spanning Tree Matching Decoder for Quantum Surface Codes
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
We introduce the spanning tree matching (STM) decoder for surface codes, which guarantees the error correction capability up to the code's designed distance by first employing an i…
Logical Error Rates of XZZX and Rotated Quantum Surface Codes
Diego Forlivesi, Lorenzo Valentini, Marco Chiani
Surface codes are versatile quantum error-correcting codes known for their planar geometry, making them ideal for practical implementations. While the original proposal used Pauli…
Quantum Two-Way Protocol Beyond Superdense Coding: Joint Transfer of Data and Entanglement
Lorenzo Valentini, Kristian Skafte Jensen, René Bødker Christensen +2
In this article, we introduce a generalization of one-way superdense coding to two-way communication protocols for transmitting classical bits by using entangled quantum pairs. The…
