About this document
Enhancing Quantum Walk Metrology by Mani Shankar Rajan is a document available to read on EtoBox.
The study introduces a new estimation scheme using split-step quantum walk (SSQW) that can achieve quantum Cramer-Rao bound in multi-parameter estimation with just one parameter related to the initial state. SSQW outperforms ordinary quantum walk (OQW) in precision for multi-parameter estimation scenarios and allows for enhanced precision in single parameter estimation by tuning the dynamics of the walk. The findings suggest that SSQW
