Quantum low-density parity-check codes are a promising approach to fault-tolerant quantum computation, offering potential advantages in rate and decoding efficiency. In this work,…
Quantum Low-Density Parity-Check Codes
Bane Vasic, Valentin Savin, Michele Pacenti +2
Quantum error correction (QEC) is a cornerstone of quantum computing, enabling reliable information processing in the presence of noise. Sparse stabilizer codes -- referred to gene…
Fault Tolerant Decoding of QLDPC-GKP Codes with Circuit Level Soft Information
Shantom K. Borah, Asit K. Pradhan, Nithin Raveendran +2
Concatenated bosonic-stabilizer codes have recently gained prominence as promising candidates for achieving low-overhead fault-tolerant quantum computing in the long term. In such…
Turbo-Annihilation of Hook Errors in Stabilizer Measurement Circuits
Michele Pacenti, Asit K. Pradhan, Shantom K. Borah +1
We propose a scalable decoding framework for correcting correlated hook errors in stabilizer measurement circuits. Traditional circuit-level decoding attempts to estimate the preci…
