Theory of "Weak Value" and Quantum Mechanical Measurements
Yutaka Shikano
TL;DR
This paper reviews the concept of weak values in quantum mechanics and discusses measurement models to extract these values, providing foundational insights into quantum measurement theory.
Contribution
It offers a comprehensive review of weak values and measurement models, connecting them to the author's Ph.D. research on quantum walks and time in quantum systems.
Findings
Clarifies the definition of weak values
Describes measurement models for weak value extraction
Links weak values to quantum measurement processes
Abstract
We review the definition and the concepts of the weak values and some measurement model to extract the weak value. This material is based on the author Ph.D. thesis "Time in Weak Values and Discrete Time Quantum Walk" at Tokyo Institute of Technology (2011).
