Measurements of non local weak values

TL;DR

This paper discusses the challenges of measuring non-local weak values using local methods, introduces a non-local measurement approach, and explores the conceptual meaning of non-local weak values.

Contribution

It presents a new method for measuring non-local weak values through non-local measurements, addressing limitations of local measurement techniques.

Findings

Local measurement methods are less robust for non-local weak values

Non-local weak measurements can effectively measure non-local weak values

The paper clarifies the conceptual meaning of non-local weak values

Abstract

Some recent attempts at measuring non local weak values via local measurements are discussed and shown to be less robust than standard weak measurements. A method for measuring some non local weak values via non local measurements (non local weak measurements) is introduced. The meaning of non local weak values is discussed.
