A Highly Accurate Fast Decoding Framework for QLDPC codes Accelerated by Noise Perturbation and Ensemble Decoding
Mainak Bhattacharyya, Ankur Raina
A well-balanced decoder has been central to the development of modern fault-tolerant quantum computing. However, the inherent topologies of quantum error correcting codes can limit…
Fault-tolerant syndrome extraction in [[n,1,3]] non-CSS code family generated using measurements on graph states
Harsh Gupta, Mainak Bhattacharyya, Ritik Jain +1
The reliability of quantum computation critically depends on the performance of quantum error-correcting codes (QECCs). Performance of QECCs can be severely degraded by hook errors…
Decoding Quantum LDPC Codes using Collaborative Check Node Removal
Mainak Bhattacharyya, Ankur Raina
Fault tolerance in quantum protocols requires contributions from error-correcting codes and their suitable decoders. Quantum Low-Density Parity Check (QLDPC) codes are one of the m…
Quantum Approximation Optimization Algorithm for the Trellis based Viterbi Decoding of Classical Error Correcting Codes
Mainak Bhattacharyya, Ankur Raina
We construct a hybrid quantum-classical Viterbi decoder for the classical error-correcting codes. Viterbi decoding is a trellis-based procedure for maximum likelihood decoding of c…
