Trapping Sets of Detector Error Models
Michele Pacenti, Nithin Raveendran, Bane Vasic
Message-passing decoders are among the most promising candidates for scalable quantum error correction, yet their behavior in the low-error-rate regime remains poorly understood un…
Impulse Decoding of Quantum LDPC Codes: Equivalence of Degeneracy and Code-Shortening
Shobhit Bhatnagar, Michele Pacenti, Nithin Raveendran +2
Quantum error correction is essential for building scalable quantum computers. Within the stabilizer formalism, the Calderbank-Shor-Steane framework constructs quantum codes from p…
Quantum Low-Density Parity-Check Codes

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…
Linear Time Iterative Decoders for Hypergraph-Product and Lifted-Product Codes
Asit Kumar Pradhan, Nithin Raveendran, Narayanan Rengaswamy +1
Quantum low-density parity-check (QLDPC) codes with asymptotically non-zero rates are prominent candidates for achieving fault-tolerant quantum computation, primarily due to their…
On the Minimum Distances of Finite-Length Lifted Product Quantum LDPC Codes
Nithin Raveendran, David Declercq, Bane VasiÄ
Quantum error correction (QEC) is critical for practical realization of fault-tolerant quantum computing, and recently proposed families of quantum low-density parity-check (QLDPC)…
