Soft Syndrome Decoding of Quantum LDPC Codes for Joint Correction of Data and Syndrome Errors
Nithin Raveendran, Narayanan Rengaswamy, Asit Kumar Pradhan +1
Quantum errors are primarily detected and corrected using the measurement of syndrome information which itself is an unreliable step in practical error correction implementations.…
A Semiclassical Proof of Duality Between the Classical BSC and the Quantum PSC
Narayanan Rengaswamy, Henry D. Pfister
In 2018, Renes [IEEE Trans. Inf. Theory, vol. 64, no. 1, pp. 577-592 (2018)] (arXiv:1701.05583) developed a general theory of channel duality for classical-input quantum-output (CQ…
Approximate Unitary 3-Designs from Transvection Markov Chains
Xinyu Tan, Narayanan Rengaswamy, Robert Calderbank
Unitary -designs are probabilistic ensembles of unitary matrices whose first statistical moments match that of the full unitary group endowed with the Haar measure. In prior…
Un-Weyl-ing the Clifford Hierarchy
Tefjol Pllaha, Narayanan Rengaswamy, Olav Tirkkonen +1
The teleportation model of quantum computation introduced by Gottesman and Chuang (1999) motivated the development of the Clifford hierarchy. Despite its intrinsic value for quantu…
On Cyclic Polar Codes and The Burst Erasure Performance of Spatially-Coupled LDPC Codes
Narayanan Rengaswamy
Polar codes were introduced in 2009 and proven to achieve the symmetric capacity of any binary-input discrete memoryless channel under low-complexity successive cancellation decodi…
Classical Coding Approaches to Quantum Applications
Narayanan Rengaswamy
Quantum information science strives to leverage the quantum-mechanical nature of our universe in order to achieve large improvements in certain information processing tasks. In dee…
