Lifted surgery: Fast processing with QLDPC codes
Lucas Berent, Lawrence Z. Cohen, Armanda O. Quintavalle
Quantum low-density parity-check (QLDPC) codes are a leading candidate for achieving low-overhead fault-tolerant quantum computing. However, the time overhead of logical operations…
QGPU: Parallel logic in quantum LDPC codes
Boren Gu, Andy Zeyi Liu, Armanda O. Quintavalle +3
Quantum error correction is critical to the design and manufacture of scalable quantum computing systems. Recently, there has been growing interest in quantum low-density parity-ch…
Computing Efficiently in QLDPC Codes
Alexander J. Malcolm, Andrew N. Glaudell, Patricio Fuentes +10
It is the prevailing belief that quantum error correcting techniques will be required to build a utility-scale quantum computer able to perform computations that are out of reach o…
Localized statistics decoding for quantum low-density parity-check codes
Timo Hillmann, Lucas Berent, Armanda O. Quintavalle +3
Quantum low-density parity-check codes are a promising candidate for fault-tolerant quantum computing with considerably reduced overhead compared to the surface code. However, the…
Transversal Diagonal Logical Operators for Stabiliser Codes
Mark A. Webster, Armanda O. Quintavalle, Stephen D. Bartlett
Storing quantum information in a quantum error correction code can protect it from errors, but the ability to transform the stored quantum information in a fault tolerant way is eq…
Partitioning qubits in hypergraph product codes to implement logical gates
Armanda O. Quintavalle, Paul Webster, Michael Vasmer
The promise of high-rate low-density parity check (LDPC) codes to substantially reduce the overhead of fault-tolerant quantum computation depends on constructing efficient, fault-t…
Bias-tailored quantum LDPC codes
Joschka Roffe, Lawrence Z. Cohen, Armanda O. Quintavalle +2
Bias-tailoring allows quantum error correction codes to exploit qubit noise asymmetry. Recently, it was shown that a modified form of the surface code, the XZZX code, exhibits cons…
ReShape: a decoder for hypergraph product codes
Armanda O. Quintavalle, Earl T. Campbell
The design of decoding algorithms is a significant technological component in the development of fault-tolerant quantum computers. Often design of quantum decoders is inspired by c…
Experimental implementation of secure anonymous protocols on an eight-user quantum network
Zixin Huang, Siddarth Koduru Joshi, Djeylan Aktas +12
Anonymity in networked communication is vital for many privacy-preserving tasks. Secure key distribution alone is insufficient for high-security communications, often knowing who t…
Single-shot error correction of three-dimensional homological product codes
Armanda O. Quintavalle, Michael Vasmer, Joschka Roffe +1
Single-shot error correction corrects data noise using only a single round of noisy measurements on the data qubits, removing the need for intensive measurement repetition. We intr…
Two-tier blockchain timestamped notarization with incremental security
Alessio Meneghetti, Armanda Ottaviano Quintavalle, Massimiliano Sala +1
Digital notarization is one of the most promising services offered by modern blockchain-based solutions. We present a digital notary design with incremental security and cost reduc…
