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…
Generating probability distributions using variational quantum circuits
Ronit Raj, Kshitij Durge, Manish Mallapur +2
Sampling from a probability distribution is a core task in many quantum and classical algorithms. Variational quantum circuits provide a natural approach to generating such distrib…
Encoder Circuit For Surface Code using Measurement-Based Quantum Computing Model
Priyam Srivastava, Vaibhav Katyal, Ankur Raina
Surface codes are one of the most important topological stabilizer codes in the theory of quantum error correction. In this paper, we provide an efficient way to obtain surface cod…
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…
Entanglement Purification with Quantum LDPC Codes and Iterative Decoding
Narayanan Rengaswamy, Nithin Raveendran, Ankur Raina +1
Recent constructions of quantum low-density parity-check (QLDPC) codes provide optimal scaling of the number of logical qubits and the minimum distance in terms of the code length,…
Construction of non-CSS quantum codes using measurements on cluster states
Swayangprabha Shaw, Harsh Gupta, Shahid Mehraj Shah +1
The Measurement-based quantum computation provides an alternate model for quantum computation compared to the well-known gate-based model. It uses qubits prepared in a specific ent…
Finite Rate QLDPC-GKP Coding Scheme that Surpasses the CSS Hamming Bound
Nithin Raveendran, Narayanan Rengaswamy, Filip Rozpędek +3
Quantum error correction has recently been shown to benefit greatly from specific physical encodings of the code qubits. In particular, several researchers have considered the indi…
Distilling GHZ States using Stabilizer Codes
Narayanan Rengaswamy, Ankur Raina, Nithin Raveendran +1
Entanglement distillation is a well-studied problem in quantum information, where one typically starts with noisy Bell pairs and distills Bell pairs of higher fidelity. Whi…
