A Proposed Quantum Framework for Low-Complexity Quantum Simulation and Spectrum Estimation of Hankel-Patterned Systems

2023 · IEEE Transactions on Quantum Engineering

The structured matrix completion problem (SMCP) is ubiquitous in several signal processing applications. In this work, we consider a fixed pattern, namely Hankel-structure for the SMCP under quantum formalism. By exploiting its structure, a lower-gate-complexity …

A complexity efficient penta-diagonal quantum smoothing filter for bio-medical signal denoising: a study on ECG

2024 · Scientific Reports

Abstract Extracting information-bearing signal from a noisy environment has been a practical challenge in both classical and quantum computing formalism, especially in critical signal processing applications. To filter out the effect of noise, we propose …
